🚨 TOP 200 Questions: Class12 Hsc PCMB मध्ये 70+ हवेत? मग हे 12 तास चुकवू नका!

0:02 Okay, let me tell you something about that. What is our... There are some people who are in our session. How many people are you? You are not supposed to be a business. Is it a car? Okay, you are. What is the matter? You are so much like this, you are so much like this, you are so much like this, you are so much like this, you are so much like this, you are so much like this, you are so much like this, you are so much like this, but I will not be able to do any more sessions, because

0:48 after that, you are so much like this, so you are ready to do English for people? Do you want to do it? It's 11 am, no matter what, it's 10 am, it's 10 am, I am happy with you, who is lucky? What happened to me? This comment is running fast, so I don't understand what I will learn, who will not learn? And one comment is long, long, long, that's the crying emoji. What is it? What is it? Let's 1.0. Rottlou, baby. Okay, let's go. What happened? No, wait a minute. I am starting 5.35

1:36 minutes I am starting 5.35 minutes I am not going to explain to me how many chapters will be there? I mean, we will talk about the most important 50 questions in biology today okay? Hello Chemistry means maths? It's not? It's biology. Okay. Everything comes in understanding? Yes? Let's go, you are more understanding. Right? Okay, okay, okay. Our session will start one

2:23 minute. We don't have any chance to laugh. It's a good thing. It's good for health. do you not understand? you are 8 hours old, you are my name very big, very good, very good, what do I tell you? I have to do this, you have to do this exam, you have to do this, you have to give such dedication, but I think it's good that I have some kids who are so dedicated, okay, let's do it, so, it's done, let's do it, let's do it, let's do it, As we complete the session, I guess we will not say the formality of our notes. Sorry, what's up? Our Pw channel. I am talking about the

3:13 app. We have to search our badge and our notes. We will do our discussion today's session. We will discuss our biology top 50 questions that have been repeated. Where did my pen go? In our top 50 questions we will discuss our first lesson in the name of reproduction and lower unhaired plants. So, the question is the structure of male gametophyte. This question is specifically the one who has asked questions. It is not like 2 marks, 3 marks, 4 marks. It is not a topic. How many hours will it? I am telling you, our session

4:02 will be 7.45. I will not take much time. We have to prepare all the content in little by little time. And you have to finish. So you also have to show me a little bit of energy. I am here, so I am here, I will keep my energy. If we ask about what is the structure of male gametophyte, then we can explain what we can do about it. And we have to explain the diagram with the diagram, so we have to remove the diagram. If you can remove the diagram from the male gametophyte, then this is the diagram that you can draw. What will we show? This is an exine, which is a simple layer. This layer is a little lower than the outside layer. First

4:50 important thing. Second important thing is, sometimes you can't get the same layer. You can't make it small because we call it germ poor. So side-by-side diagram, we need to make it. What is the first thing? What is male gametophyte? We tell you that our pollen grain is पोलन ग्रेन का ही दूसरा नाम है मेल गेमिटोफाइट हमारे जो प्लांट्स है प्लांट्स में जो एंथर होता है एंथर के अंदर एक स्पेशल सेल होती है जिसका नाम है हमारी पोलन मदर सेल ने मियॉसस किया उससे माइक्रो स्पोर बने माइक्रो स्पोर आगे जाके डवल�

5:42 There are two things in the spheroiderm. Which one? The first layer is the exynes which is made by sphero polenum. Somewhere in the sphero polenum is absent or very thin. It is called germ pore. This is our second form. And this germ pore is formed in the tube. Second, what is our inner layer? What is entine? This is our entine layer. okay bylaw.. okay entine layer is cellulose and pectin okay don't remember both sporo polenum and cellulose and pectin okay after that we talked about outside and inside we talked about inside

6:30 inside inside this is a big structure that is one big cell which is called vegetative cell और सबसे अंदर वाली यह चोट उसी जो सेल तोंगो नजर आ रही है थिस वन किवाली वाली वांसी हमारी जन्रेटिव सेल करेक्ट है दोनों के पारे में बता दो दोनों सेल है वेजिटेटिव भी है जन्रेटिव भी है यह चीज बता देने वेजिटेटिव सेल आगे जाके क What will we do with our pollen tube? How much we should tell? Correct! If we have questions for 4 marks, then we will make this diagram together.

7:17 Why did you say that? Yes, it is on the same page. Sorry, we will make this diagram together. 2 marks are coming. If we have questions for just drawing diagrams, then we will make just so many diagrams. And if we have questions for 4 marks, then we will make just so many diagrams. Right? Correct! What marks are these? Brother, you should have to take this doubt. Do it with a smile. Okay? It will go on our time. Otherwise, I don't know what happens after exam. If you take it, you get something. Okay? Okay. Chinu, hello. How is it? Next, our structure is again. It is a very

8:06 repeated type question that is describe the structure of anatropous oval. Now the structure of anatropous oval is the diagram specifically asked for 2 marks and the diagram plus explanation also asked. So here you can see this is our female gametophyte. Female gametophyte structure means a structure in which female gamet develops. So when we write the answer, we need to give a little introduction. When you get to meet someone first, you don't need to impress yourself. But you don't need to present yourself properly. Especially if you want to impress

8:53 yourself, you won't go to bed. तो पुछ करोगे अवतार तो ठीक रखोगे अपना अंसर शीट भी वैसी ही रखने का है इसको थोड़ा सा इसका प्रेजंटेशन अच्छा रखना है क्योंकि भाई साब हमको सामने वाले को भले हमको जादा ना आता हो लेकिन दिखावा तो करने का है ना एक्जाम पेपर में

10:26 Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello Hello So, what was the question? Yes. We were talking about the structure of anatroposal. So I was wondering if you were to check the paper and impress yourself a little bit. So first, let's give an impression. How do you give an introduction? You mean, you said it's our answer. The structure of the female gametophyte will be made.

11:16 Female gametophyte is well protected. Basically, it's well protected. I mean, there are two covering on it. Which covering are our integument? Correct? Next, what will we tell you? Below these two integument, we have a special parenchymas layer. Correct? What do we call these cells? These are a nucellus cell. Next, what is our layer? That is layer of nucellus. Inside the nucellus layer, now comes our female gametophyte structure. Original female gametophyte is called as embryo sac. No, but you asked me about anathropous oval. Sorry, sorry, sorry. I thought I was talking about gametophyte. Sorry, my mistake. If you have to tell about anathropous oval, you can also say that it's an impression that

12:07 anathropous oval is the structure in which female gametophyte develops. I'm not saying much. Okay? Let's go. So, this is our basic structure. We call our embryo and female gametophyte. Now, if we tell the whole anotropous oval structure, we have told that the outside of the two layers are the protective layers. Under the lower layer, that is the new cell's layer, the structure is representing our embryo sac which is a 7-cell, 8-ucleated structure. Correct? Here, okay? Let's go. What is the look of our whole structure? It is attached with the ovary

12:55 wall. this is called as hylum sorry this is called as funicle and this is our structure or integument where one another connects this is called as hylum So what we are doing in the diagram? What should we do in our answer? Our diagram and answer should not be different. It should be the same. So what should we do here? Explain it. If I go

13:41 to explain about this, then what will I tell you? Our ovule is where is developed in our ovule? And what happens? It remains connected to our ovule Here is a small structure which we call placenta. Correct? First explain. Start from below. Okay. And this is a stock-like structure. What is this? This stock-like structure, this is funicle. Correct? Yes. Then we have said that where the funicle is our, the structure is on the top, that is the phylum. Anatropous oval is downward directed downward directed means its micropyle is shown below what we will say after that?

14:27 that our oval is the parent gametes cells in which we have a mega spore mother cell that is our new cellus in the new cellus is the power of the new cellus we have to draw it that's right तो इस तरीके से हमारा यह जो सवाल है अज टोल्ड यू डाइग्राम भी दो मार के लिए सकते स्पेसिफिक सेपरेटली डाइग्राम प्लस एक्स्पेनेशन अगर पूछा जाता है तो वह तीन या फिर चार मार के लिए पूछा जा सकता है मेरी अवास बहुत कम है अब रहे �

15:22 मेरा सेशन में नहीं दिख रहा मुझको खुद को भाई साथ क्या दिन आ गया ऐसा नहीं होना है हमको इस उमें टाइम नहीं गवाना है ना भाई साथ मेरे पास में टाइम कम है वैसे भी अभी ठीक है अवाज गेमिंग गल आपके बारे में अच्छी बाते बतानी है बात करें I will focus on the CTS, I will focus on the CTS lectures. Okay, I will hear the sound. Where is the person? Are you coming?

16:09 Thank you, thank you, thank you so much. Please tell me. After that, I will be able to do this lesson. we can ask our question now we have asked our angiosperms which is developed in this type of endosperm we know that there are three different types of endosperm which are developed first endosperm that is nuclear endosperm second cellular cellulose is halobian three of them have been specialized here I will explain you from the diagram First, what is our nuclear endosperm? As you know, our ovule structure

16:56 is the whole embryo. We know that there is synergied, antipodal, etc. The fertilization is here. Correct? Let's say, here we have our zygote. When we have egg and male gamete fuse. And we have to say that primary endosperm nucleus by triple fusion. Correct. Primary endosperm nucleus is made by our male gamut plus secondary nucleus. What is secondary nucleus? Our polar nuclei are made by another one and secondary nucleus. Correct. They are made by our primary endosperm nucleus. Now, what is our primary endosperm nucleus? What starts inside

17:44 this? nuclear division, free nuclear division, what it means is free nuclear division, it means that nuclear division will divide only and cytoplasm divide not. When it comes to such conditions, it means free nuclear division. So if our primary endosperm nucleus continues to be divided in continuous free nuclei, then we call it nuclear division and this is the endosperm form. We will call it nuclear endosperm. But I have to remember one thing. The nucleus has become. After a while, after a while, there is a big vacuole created. And after, what happens in a cell surrounding? A cell wall is formed. Not all of

18:31 the cells. Only in the peripheral cells surrounding the cell wall begins. Let me explain again. What happened in nuclear endosperm? Our nucleus was सिर्फ nucleus divide कर रहा है, cytoplasm divide नहीं हुआ, first thing, second important thing, vacuole का formation हुआ, है ना, तीसरी important thing, जो peripheral cells है, उनके surrounding में cell wall का formation शुरू हुआ, ठीक है, पर इंटर्नल cell जो है, वो nucleus, sorry, internal nucleus जो जैसे कि वैसे ही रहते हैं, उनके surrounding में wall form नहीं, wall form नहीं हो रही, ठीक है, तो वही क्या गएते हैं हमा Okay? Generally, you get to see a endosperm in your coconut. Second type of endosperm is

19:17 cellular type of endosperm. Cellular endosperm is simple. What was it before? Primary endosperm nucleus. Primary endosperm nucleus has divided into 1 cell. It becomes 1-2 cells. 2-4 will become 4-8-8-16. Here, from the first division cell, it becomes a complete cell. It is not that it is not a free nuclear division, but it is not a cell wall. If it continues to happen, it is called a cellular type of endosperm. And the last thing is called a halobial endosperm. What do we mean by halobial endosperm? So, let's take a look at our beginning of primary endosperm nucleus. It was a single cell structure. It was divided into two cells. ठीक

20:07 है, दो सेल्स कौन सी, जो हमारी बड़ी वाली सेल है, that is, mycopylar cell, और छोटी वाली जो है, that is, our chalazal cell, ठीक है, ये दो सेल्स फॉर्म हुए, दोनों independently क्या करती है, free nuclear division करती है, मतलब सिर्फ nucleus form होंगे, फिर उसके बाद में हमारा, mycopylar cell है, उसमें cell wall का formation होता है, अब मौडल आंसर केसे लिखना यहां पर मैंने तुमको अल्रेडी आंसर दिया यह बाद में आप पीडियेफ जो है मारे यह चेक कर सकते हो जो कि आपको मिलेगा हमारे अप में ही है ना तो यह मारा तीन मार्क का सवाल जो है तीन मार्क या फिर कभी-कभी एंडो स्पर्म को ड

20:56 You can write 8-10 points depending on the question. What is the demand of the question? Now, the question is our demand to explain the endosperm. First, we define what endosperm is. And, tell us about 3 points. If you are getting 3 points, that's a different issue. Okay? Then, the number of points will increase. We will tell you 3 types explain. We will tell you 3 types. We will tell you more. Okay? If you are not, you will tell you more. What is this? Okay, next one is our question. That is regarding explaining the contravences used by plant for cross pollination. Our angiosperms are not an sexually reproducing organism. They generally prefer autogamy.

21:44 They want to prefer cross pollination and sexual reproduction. We won't say sexual reproduction. Those are sexually reproducing organism, they generally prefer self fertilization avoid cross fertilization with other organisms, reproductive fitness is made of vigour so that is why cross fertilization is mostly preferred now cross fertilization should be made of plants so what is different from plants correct one step is correct one step is correct first one technique that we use the plant is diichogamy what is the meaning of the difference between both of the two of the two of the two of the two of the two of the two

22:51 of the two of the two of the two of Our plants are in their reproductive structures especially male and female reproductive structures. They will develop at different times. Don't give self fertilization. In the plant, you can't give female reproductive structure and male reproductive structure. What do you do? You can mature both in different times. You can do the first marriage before the other. तो अगर पहले हमारा male gametophyte और male reproductive structure अगर पहले mature होता है तो उसको हम क्या कहता है proto-andry जहां पर क्या हुआ androsium androsium मतलब जो male part वो क्या होगा पहले mature होगा जो हमको दिखता है हमारे sunflower के disc florid में

23:39 Sunflower is a big structure in which there are two different different flowers. One is Ray Fluorids and the other is Disc Fluorids. In Disc Fluorids we see this first thing. The plant is going on. No, it's not like it. It's different from our own. It's different from our own. Let's go, second one is Gynosium sorry protogyny but if Gynosium is first developed then we will say protogyny okay so protogyny is the case of the glorious name of the plant in that it is looking at that if female reproductive structure is first developed then correct? next that is prepotency what do we mean by prepotency that if the

24:27 other flower is on the same, if the other flower is on the same, then it will germinate first. We call it pre-potency. We generally get to see this in apple. The pollen grain from other flowers germinates faster. As I tell you, my mother and father tell you something good about your mother and father. But if you tell your friends, तो क्या है अपन जल्दी सुन लेते हैं बोलाओगा दोस्तने तो सही बात होगी है ना मम्मी पपता रहे तो आपन इग्नोर करते है मतलब घर की मूर्गी दाल बराबर इधर भी वही गानी है फुद का वाला पोलन ग्रेन आके बैटा तो उसका कोई वैल्यू नहीं है दूसरे

25:25 and stigma and stamen and carpal structure same plant if they don't need to get them together they should not be fertilized in them so they have physical barriers to them tell me they have big walls and big walls so this structure is called the contrivance where there is a physical barrier between the If there are two reproductive parts or the gametes, if they are not coming in contact because of this physical barrier, it is said that the gametes generally see each gamete in Calotropism. And the last one is self incompatibility. Self incompatibility means

26:15 that if you are alone in the same polarity, if you are sitting on the same flower stigma, then that stigma will reject it. its proteins will not match its own way its own way its own way its own way its own way its own way its own way its own way its own way its own way its own way its own way its own way Next, my point is that is Animophily. Animophily is also about this because you will get

27:02 PDF free and the session will be completed. After that, you will get our PDF free and you will get our PDF free. I have included the model answer here directly. If you have a little more time, I will tell you myself. But since we have a little less time, we have to complete it too. So, we will complete the time bound. So, what I was saying? Yes, the reason for animal philly is more questions. That's why the reason is that our child has been taught for years and we are not talking about animals. But our child the same thing that I have not

27:49 studied in the year. The same thing that I have said in the year, I have said that it will go straight to the animal. I have no idea. But this logic is not going to work. So the confusion created and confusing topics are very good. I like the examiner to set the paper. If you have checked the paper, then leave it. Set the paper. If you have not given the paper, then how will it go? we need to play with someone's problems so this is why this is generally a question so animophily means that animal through is not happening here is what happens here? which thing happens if pollination is through

28:38 the air? if our plants have used the wind for pollination then we call it animophily okay then after that we asked about this, what is the adaptation of this animal fillers flowers? what is the speciality of this? so the first thing is the flowers, they will be small, inconspicuous, they will not impress them, they are colorless, they are not transparent in biology, they will be green, they will be green flowers This flower is not a good food, it is not a good food. It is nectar-less, fragrance-less. The

29:25 third important thing is pollen grain. Pollen grain is a little full, so what can it be in the air? It can be in the air. It can be in the air. It can be in the air. It can be produced in the air. Stigma is a very large number. How do we write it? First, we have told flower speciality. Then, the poland grain of the speciality. Stigma is a speciality that is called feathery type of poland grain. After that, we have told stamen about stamen and poland grain. Stamen is exerted and is also out of the state. It is versatile. Versatile means that it can show a little bit of movement. इसका इसका इसका

30:15 इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसका इसक आपका इंटर्विव किस चीज का वाल दे बेस्ट जो भी है आपका अकल वाल दे बैस्ट ठीक है ओके पर इस टैप ओ पॉलिनेशन अब भाइस आप पॉलिनेशन को पहले तो डिफाइन करेंगे है ना क्या होता है पॉलिनेशन इस ट्रांसफर पोलन ग्रेंट फ्रॉम आंथर

31:14 and zeno-gamy. Correct? If you want, you can make a diagram. Correct? If you have time, don't make time. What will you make in autogamy? What happens in autogamy? This is our flower. Right? And this is our flower. Stemina and carpal are developing. Correct? Think of the same pollen grain of the same flower. It is germinated on the same stigma. तो तो तो तो पॉलिनेशन इस कॉल फॉटो गयामी जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है जो है �

32:13 So, remember these pollen grains, these plants are on our first flower stigma. So that is Guytono Gami and third is Xenogami. So, what happens in Xenogami? In Xenogami, there are two different plants, same species, but in the same plants. What happens? It will pollination. Here, that is the two flowers that we are looking at and these are the same species but they are coming from different plants so if they pollination is in it then that is xenogamy correct examples here note this

32:59 is it okay then after this next lesson which is asking questions is our reproduction in law and higher animals Now let's see a quick question. Next question is our next question. I'm asking human testes to explain histology. Histology means that the tissues are there. Tell us about the tissues. Correct. So this question is also possible. If I used histology, I will tell you how to describe the TS of human testes. So what can we tell human testicles? We tell one thing that we have

33:44 one testicle inside each testicle we find that there are approximately two to three hundred testicular lobules. If you don't want to start here, first you call transverse section. You call the testicle laser. So the section created, that is why. Okay, I tell you, some eggs are made, right? You eat eggs, right? Egg, what is an egg support? If you cut it from here, correct? So what does it look like? If you look at it from above, right? So you see this yellow part in the beach, our egg yolk. And this outside is the egg white. Correct? So this is the transverse section. okay so if you think the testicle is transferred

34:33 section of the transfer section of testicles we know that it has three different layers protective layers on the top of the skin tunica vaginal is tunica albu genia and the third layer that is the third layer is the third layer one more reticularis, reticularis, sorry. Who was the third layer? The most outside vaginalist, second albu genia and the third layer is the third layer in the comment section. So remember someone, third layer is the third layer in our testicles. Thank you so much. So this is our vascular layer.

35:19 These are three different layers. Then let's see about it. basically tunica albu genia what does it do to testicles like 2 to 300 different compartments break these are called as testicular lobules inside each testicular lobule we look at 1 to 4 semi-famous tubules 1 to 4 highly coiled semi-famous tubules are present now this is our semi-famous tubules यहां पर हमको क्या दिख रही है यह cuboidal cells की layer नजर आ रही है यह cuboidal cell की layer है and in between this cuboidal layer यहां फिर आप इसको germinal epithelium भी बोल सकते हैं यहां क्या दिखेगी यह triangular सी हमारी cytoli cells नजर आती है correct which are used for nourishment of developing spermatozoa चिक

36:07 है ना ओके चलो after that we have told that the seminiferous tubule is on top of the stem and it is a continuous layer, we will not say continuous because what is present in it is our sertuline or sustentacular cells, correct? then after that we have our germinal epithelium it undergoes gametogenesis गेमेटोजनेसिस मतलब यही लेयर से क्या वनेंगे हमारे गेमेट्स बनेंगे मेल गेमेट्स बनेंगे रैइट जिसको हम क्या कहता है स्पर्माटोजोगा कहता है अच्छा सैटोली सेल क्या कर रही नरिश्मेंट प्रोइट कर रही हमने बताया और यही टेस्टिकल्स में हमको

37:08 स्टाइटिंग विद प्राइमरी स्पर्माटो साइट सेकेंडरी स्पर्माटो साइट स्पर्माटेड स्पर्माटो जो हम ग्या बूल सकते हैं जो लूमेन है सेमिन फिरस्टीबिल का यह जो लूमेन है यह लूमेन वाले लेयर में हमको क्या नजर आएंगे मल्टिपल स्पर्म Correct? It is not different from our explanation. And tell us a little bit outside of the seminiferestible, what do we look at here? These little cells look at them. We call them the laedic cells or interstitium present. That is why they are also

37:55 called interstitial cells. Correct? Let's go. After that, our next structure इसका डाइग्राम हमको बताना है अब देखो अगें सवाल सिर्फ डाइग्राम के लिए आता है तो दुमार का सवाल आएगा एक्स्लेनेशन के लिए तो तीन या फिर चार मार के लिए सवाल बन सकता है फंक्शन ओव साटोली सल साटोली सल का फंक्शन है डेवलपिंग स्पर जिसको हम कहता है तेस्टोस्टेरोन उसको प्रेड्यूस करना तेखें वालिगल और एग में आपको अपन्फूजन हो रहा है बेटा ग्राफियन फॉलिगल के अंदर सेकेंडरी उसाइड डेवलप होती है सेकेंडरी उसाइड बाद में एग बनाती है तेक है आप एक काम करो �

39:01 I will explain it a little later. What is the structure of the head? This is the head region. Is it spermatozoa? Spermatozoa is the head of the head. What is the head of the head? a small vacuolar structure is present which is called acrosome and just below the acrosome there is this male nucleus correct? the spermatozoa nucleus is just under the head region

39:48 after that there is a small neck region under the head or the head is not the spermatozoa also the spermatozoa is also the spermatozoa यह गर्दन में क्या प्रेजन है हमारा जो स्पर्माटो उसके सेंट्रियोल प्रेजन दोनों सेंट्रियोल नेक वाले रीजन में मिलेंगे अच्छा थर्ड इंपोइटन तिंग गर्दन की नीचे वाला जो हिस्सा है यह जो मिडल पीस अब यह मिडल पीस इसका स्पेशालिटी So what's your book called? Mitochondria, which is in our spermatozoa, has given a

40:33 different name. What do we call it? They are called Neb and Kern. We will speak straight, not straight. We have to add extra extra things to our children's mind. So what do we call it in the middle part of the Mitochondria and Spermatozoa? Neb and Kern. It's really arranged, correct? I don't know about the arrangement. Correct? So here is our spermatozoate. What happens after that? Next one will be our structure. That will be the tail. This is a flagellar type structure. Correct? This tail is extended. It's a long

41:21 tail. And this tail has helped the movement. Correct? So, this is the structure we have told in the diagram, we have to write it here. We have to write something different, check it out. Sperm is representing the male gamut, motile and microscopic. We have given the knowledge that we have known as a structure and such. Then, we have told that we have divided it in different parts. What is the head region? It is the oval shape. It is the shape we have told. In that first we are looking at the vacuolated structure which is called acrosome and in acrosome there are enzymes present in hyaluronidase and the other that is our zonalicin these

42:11 enzymes are present in acrosome. Second thing we have told what we have told and the nucleus is under the next neck is a small neck which is present in our centriole present proximal and distal centriole middle piece is our middle piece is exil filament that is continuing from distal sentryole and here we have 10-14 mitocondria which we have given a name name name and tail is a long tail is tapering on the bottom of the side is very low in it so it works like a flagella and it helps to move it if you put your mind to the point then there will be no difference Next we have a

42:58 question. Explain what you asked. We have different steps to explain. Let's go ahead and give you a hint. If I have written Ogenesis, it will be possible to ask Spermatogenesis. Spermatogenesis and Ogenesis. If I have written Ogenesis, So what's happening? There are three stages. Who comes in our hematogenesis? The first step is multiplication phase. Second is growth phase and the third is maturation phase. When someone was confused, right? In a graphene follicle and egg cell, look at this

43:47 simple example. In the ovary, many follicles are present. I won't write all of this in the answer. I'll explain it to you. and there are many follicles in the overraceous. What does follicle mean? It's a full structure. Imagine the follicle is full. What is the full structure? It's a paper. And in the center, there is something like this. The center of the circle is our oocyte. Okay? The center of the structure is called oocyte and the outside of the full is what is it? It's a full structure of follicle. Why do you have a lot of work on follicle? What is the following? The growth show. If this is primary follicle, it will develop secondary follicle.

44:33 Secondary follicle will develop from the tertiary follicle. Then, the graphene follicle will develop from the tertiary follicle. How does it happen? I will discuss a little bit. I will discuss this. In the graphene follicle, this was oocyte. This is oocyte. Which is secondary oocyte? Where is secondary oocyte? प्राइमरी उसाइट ही अपनी वहीं मियॉसस करते हैं सेकंडरी उसाइट बनाती है अभी बात करते हैं इसकी देखो इनीशली क्या हो रहा है माल्टिप्लिकेशन फेज में जो हमारी प्राइमरी जर्माइनल सेल्स है या फिर उसको प्राइमोडियल जर्म सेल भी बूल सकते हो

45:20 Gamet mother cell or which we can call O-gonial cells. This is a multiplication phase. What will happen in multiplication phase? Mitosis. The second phase is growth phase. There is no division in growth phase. The growth phase is our cells. It's only growing our size. What do we do in size? They didn't divide, they stopped the division. What happened in primary oocyte? It changed. What is the full oil surrounding primary oocyte? What is the full oil that is doing? It is produced full follicle. Now, see. What was the primary oocyte

46:07 inside? What happens to this oocyte? What happens to this oocyte? When it is mature, it will go to meiosis. जब यह हमारी primary oocyte meiosis 1 complete करेगी है कि अपने पास में डायग्राम येस में देखना हूँ यह हमारी primary oocyte जब meiosis 1 complete करती है तो यह दो unequal cells बनाती है बड़ी वाली हमारी secondary oocyte छोटी वाली first polar body यह हमारे primary oocyte के बिल्कुल चिपक के रहती है यह हमारी secondary oocyte के बिल्कुल पास में रह in its surroundings the layers are in our zona pellicida, cellular layer, corona radiata,

46:53 but why is our secondary? sorry, our first polar body is in the second oocyte in the past, okay? we have first miosis because we are talking about multiplication phase, when will we talk about the second miosis? second miosis will be completed when spermatozoa entry will be entered. When the spermatozoa is in the same way, the whole corona radiata and zona pellucida specifically, the zonopellucida has crossed the spermatozoa. The second ucite is what is done? Meiosis II completed. After completion of meiosis II, what is done? Ovum

47:38 and second polar bodies. Correct? So we have to write this thing here. We are seeing the diagram here. Correct? Then we have our next question. That is, what is placenta? What are the various functions of placenta? What is placenta and what is the function of placenta? Who is the placenta? I will tell you something. When we were in school, we had a question of placenta. So, someone didn't remember me, I didn't understand anything at that time. Honestly, I don't know what to do at the lecture time. You know what to do at the lecture time. You

48:26 know what to do at daydreaming. Teacher will give you the knowledge to your teacher. You know, your mind is just wandering somewhere else. Correct? I don't know what to do at the placenta. so at that time, like me, all of us were so when someone said that there was no pipeline in my mother's stomach, she said placenta. Now tell me, the child has told me what is pipeline and how will it be written in the words? So I don't know what to write the question, but... I don't say the pipeline, the placenta is the umbilical cord, correct? The placenta is the structure, what is this disc-like structure?

49:17 This is the female and fetus, mother and fetus, and one single organ develops with both tissues. We call it placenta. जो फीटेस है फीटेस की जो कोरियोन वाली लेयर है फीटेस के साइड से कोरियोनिक विला है और मदर की साइड से यू टराइन विला है यह दोनों चीज़े क्या करते हैं फिंगर लाइक प्रोजेक्शन बनाती है एक दूसरे के साथ में जुड़ जाती है और तोगेधर देफ in which place the placenta developed? the fetus is playing somewhere somewhere,

50:05 sometimes the placenta can develop here in this region, so here the fetus is playing here, you know you have to do a jump, a jump, a jump, a jump, a jump, all this work, so from here the fetus will reach the nourishment, this is the umbilical cord, so now your placenta doesn't look like your mushroom, but understand, don't look like your ancestors, don't look like mushrooms so fetus if we have to reach something or if we have to get unwanted things from fetus so for that placenta is there so what are we going to do? how is this structure? flat discoidal organ which represents a structural and functional connection between fetal and maternal circulation fetal and maternal

50:53 tissues are made from a specialized structure first thing it is attached to the wall of uterus and baby's umbilical cord this is what we have made our tube like our mushroom pipeline, okay? okay, it's functioned by placenta the best thing is that placenta will get oxygen second important thing is that fetus will get nourishment because the child can't eat anything in the uterus प्रेश्पिरेशन नहीं कर पा रहा है तो फॉर्ट परपेस्ट प्लासेंटा इस देर अच्छा प्लासेंटा ऑल्सो क्या करती है यह हॉर्मेंट भी सिक्रेट कर देती है तो दाट प्रेग्नेंसी मेंटेन रह सके जैसे हुमन को रिवानिक गौनाड़ोट्रोपिन है प्रोजस

51:56 It is a little bit of estrogen and in a little bit of parturation, it can be a little secret of the ovaries. Generally, it will be a little release from ovaries. This is my placenta. I am going to tell you something else. In the fetus, the unwanted metabolic waste creates the fetus from maternal circulation. This work is only the placenta. Correct? By the end of the first trimester, progesterone is made of placenta. Correct? And all hormones are maintained and maintained. So what did we tell you? Exchange. Exchange is what? Hormones, nutrients, gases and excretory materials.

52:44 For that, placenta is useful. And what is the placenta itself? Hormones production. Correct? Ambrella? You are showing me mushrooms, how can you show Ambrella? Good, it's also Ambrella, but you are like Ambrella, but you are dancing like this? Which Ambrella do you want to take? Your own Ambrella is right, you want to take a small Ambrella, how do you do it? Okay, okay. please don't take fast, time is too late and I will be here to tell

53:32 you something about my marathon, I will be able to take a little bit of detail, I will be able to take a little bit of detail, I will be able to take a little bit of detail, I will be able to take a little bit of detail at 7 am, so I will get to the beginning of the chapter 7-8 in the beginning आठ चैप्टर में लेती हूं और नाइन्थ चैप्टर से फिर अंकीता माम लेगी ठीक है तीन तारीकों होगा मैरतवान तीन तारीकों वहां मस्ट डीटेल में पढ़ेंगे अभी अपने को सिर्फ सवाल देखना है वाइज यह वाले टॉपिक से यह वाले सवाल तो एटलीस् If you start from the ending, you will start with the next one. We will

54:19 start with the marathon, which means I will start with the last one. I mean, I will start with the last one. Then, I will go up with the last one. Okay. Then, see, describe the structure of graphene follicle. Okay. We have asked the structure of graphene follicle. It is a very simple structure of graphene follicle. As I already told you, which cell in the middle of our cell? यह है हमारी secondary oocyte और इसी को प्रोटेक्ट करने के लिए वाई सारा ताम जाम चल रहा है तो ताम जाम कौन सा है secondary oocyte के उपर जो plasma membrane का layer होगा उसी को बोला जाता है उसी को बोला जाता है येस वाइटलाइन membrane ठीक है देखो तुम जब graphene follicle को explain करोगे तुम बाहर से

55:06 भी शुरू So if you have to make a diagram, start with any of this, it is fine. If you make it and see it, then start with it. Because it makes perspective good. This is our secondary oocite. Secondary oocite is the first polar point. This is our layer. Which one? This is our zona pellucida. In the surrounding of the zona pellucida, now here, यहां पर रही है हमारी को अब काम करते हैं नहीं बनाते हैं बहुत टाइम लेगी है अपने को दो मिनिट से अंदर डाइग्राम बनाने है पेपर के टाइम में तो यह हमारी को रोना रेडियेटा जो है इसके सराउंडिंग में हमको यह फ्लूएड फिल्ड ग्याविटी नजर

56:11 and we see the antrum outside the side of the cells that we see, which cells are? follicular cells I have also added a layer of follicular cells outside the thika layer, thika also has two layers this is thika internal and thika external do not do anything, do not do anything, do not do anything, do not do anything, do not do anything, do not do anything, तो थोड़ा सा ये एक पाटन बना दो जिससे हमको डिस्टिंक्शन समझे यह गया है भाई साब यह बाहर वाली लेर है जो अपन कहेंगे थीका एक्सटरना अंदर वाली जो लेर है इसको आप क्या गड़े आड़ा दिखा देते है अलग तो लगना चाहिए ना एक ही कलर से इ

57:06 what is the right internal? estrogen. Okay, what is the right internal? Which layers are our? This is a follicular cell. Let me write. Follicular cell. Okay? Then there is cavity in inside. Now you can do a little bit of color, so you can do it. But don't do it. If you do it in time, then leave it. Don't do the makeup. यह जो cavity है क्या नाम दिया हमने इसको antrum गरेक्ट अंट्रम के अंदर यह जो layer है यह कौन सी है फटाफट बोलना यह हमारी corona radiator ठीक है फिर zona felucida यह वाली जो cell लग कौन सी थी secondary

58:08 and together this is the whole structure we call this as cumulus oophores secondary oocyte we don't do our drawing good, bad, bad, we don't tell examiner's this is our structure graphene follicle which I have drawn to you Either start from inside or start from outside If you start from outside, what will you tell us? That the graphene follicle shows the layer of or the external layer of theca-externa and let's tell you this, let's tell you from the other way The graphene follicle shows the external layer of theca The theca layer is divided into two sub-layers The theca-externa which is on the outside and the theca-interna which is

58:59 present just below the theca-externa Thika interna is responsible for production of estrogen. Knowledge is given. Okay? Then we will write it down below. Inner to Thika interna there is a layer of follicular cell. Okay. Follicular cells secrete the fluid which is present in the cavity called antrum. Correct? What does liquid name the liquid? The fluid secrete by follicular cell is called liquor follicular. Okay? after that we will write one side of this graphene follicle we find cumulus ophoress contains the structure

59:45 of outer layer corona radiator inner layer zona pellucida inner to zona pellucida we have secondary o site lined by white line It's finished, the structure is finished, the diagram is finished, the explanation is finished. Okay? The diagram is made, the only way to write it is not going to go there. Okay? I need to keep control. After that, I'll see. This question has been a lot of times. What's the question? Explain to the ovarian cycle. What should you do for 60 out of 70? You should read it, don't

1:00:32 you? Who is this? Ovarian cycle, right? In the physical, there are 4 events. First, tell us to our examiner. We know which 4 phases are. First is the menstrual phase, second is the follicular phase, third is the ovulatory phase and fourth is our secretory phase and luteal phase. Tell us. Keep simple things. What is happening in which

1:01:19 phase? First, what is menstrual phase? What is menstruation? It means bleeding. uterine walls shed off if you don't remember then simply uterine wall shed off that uterine wall is shed off out of body shed out of body which is called menstruation if you remember the name then tell the name the endometrium of uterus is shed off out of the body, if you remember the name, what do you remember? uterine wall, okay? no one will say anything, if you don't write a word, you will not mark it, okay? what is happening in that

1:02:04 situation? tell the duration, you know, the endometrium is going to be on the endometrium, what is happening in the ovary? follicle just will start to develop the second phase that is proliferative phase and follicular phase How long is this phase going? From 5th to 13th day What will happen in this phase? What will happen in both places? What will happen in uterus or ovary? What will happen in uterus? It will start to build yourself under the influence of estrogen What will happen in ovary? What will happen in follicles? What will happen in follicles?

1:02:51 What will happen in the secondary follicle? Secondary follicle will develop into tertiary follicle Tertiary follicle will develop into the graphene follicle What will happen in your graphene follicle? What will happen in the antrum? What will happen in uterus? No, it will build your own uterus Then, next, our phase is ovulatory phase What will happen in ovulation? where secondary ucyte will be released outside of the graphene follicle and ovary ovulation is done which occurs somewhere around 14th day and then after that the next phase is luteal phase in the luteal phase we will tell both changes in the ovary as well as in the uterus in uterus nothing is happening in uterus only in your

1:03:38 building what is happening in the ovary remaining cells of graphene follicle develop into the corpus luteum which produces or mean called progesterone. In case of pregnancy, corpus luteum will persist but in absence of fertilization, the corpus luteum will degenerate into corpus. L begins and next menstruation will start. Correct. It's not done. It's not done. 4 marks. If we have 4 marks, if we have 2 pages, 4 pages, then we will not get 4-10 marks. the demand is the same as the answer. Okay? Did you understand? Okay.

1:04:30 Incomplete dominance can come for 3-4 marks even for 2 marks. Okay. So here, let me tell you in the incomplete dominance. In the live chat, tell us which example we have given us. In the book, which example is given to incomplete dominance? I ignore it, what? No, no, let's understand the whole thing. We have to complete our session until 7.45, because 8.00 pm will start English session. So, I have to understand that. I will not ignore it. Next, our question is regarding incomplete dominance. which example we have given to you in the book? Fet effort answer! Yes, incomplete dominance, which

1:05:20 flower is red, white, pink? You know that you know that snapdragon is given in NCIT State Board, which example is given? Mira Village Jalapa, 4 o'clock plant, very nice! जो लोग NCIT पढ़के आए ना मुझको माल होगा तो snapdragon बोलोगे है ना गलत नहीं है वह भी सही है पर अपने किताब जाना स्टेट बोर्ड वाली वहां पर उन्होंने snapdragon का example नहीं दिया उन्होंने मायरा बिलस जलापा का example दिया है ठीक है चलिए तो क्या हो रहा है भाई साब � So why we tell you that in incomplete dominance both alleles are allelum and what is the same as the

1:06:09 other one is partially expressed. When alleles is the same as the other one is not suppressed. In such case there is an intermediate expression of F1. Whatever is our hybrid, the two parents will look at the structure of the other. structure or color now let's see here what is our plant in this plant what is showing? homozygous dominant condition or homozygous dominant condition shows presence of red colored flowers homozygous recessive condition shows presence of white colored flowers in both parents when we crossed them as we see here in

1:06:57 them when we crossed them F1 hybrid जो हमको मिला वो कैसे दिख रहा था? पिंक दिख रहा था जब F1 hybrid में ही हमने selfing करवाई correct? तो हमको क्या मिला? 1 red, 2 pink and 1 white ऐसे plant मिले? नीचे में लिख दो, genotypic, penotypic ratio which is both 1 is to 2 is to 1, है ना? okay incomplete dominance is a simple example and I am telling you more questions questions from the co-dominance and incomplete dominance. okay? okay then we have which disorder is caused due to non disjunction of 21st chromosome? who will tell the answer? then we will list our characteristics. me? will you tell us? incomplete

1:07:46 dominance definition अरे भाई मिल जाएंगी नरे रुको तो घदम तो ने दो माइक थोड़ा साब क्या करूं पास मेलू अवाज अभी भी नहीं आरे अब यह अब यह अब यह अब यह अब यह अब you can write 10 points. Yes, you will get a recorded version, don't worry about

1:08:33 it. Okay? Okay? Okay, now. 4 o'clock. Yes, yes, yes. Okay, the answer is because of the 21st chromosome non-disjunction. What will create? Trisomy will create. So, 21st trisomy is Down syndrome. Correct. So, the person who has a Down syndrome, what do we look at in that person? So, first of all, we will find that there is an extra chromosome on 21st number. Correct, 21st pair is one chromosome extra. Due to which he is a human, we see many phenotypic physiological changes. Correct. Now, which changes are? First of all, face is a little broad and flat type face. Correct. The eyes are flat.

1:09:22 the eyelid is present like a monolid right? the eyelid is always smiling type of eyelid tongue protruding in certain cases the palm is a characteristic palm crease, single crease, single line on each palm there are no lines present correct? why is it not good? skeletal development is not good, it is poor they have flat hands and stubby fingers palm is present in this single palm crease these are the characteristics of her down syndrome you want to know more about her that she has identified her but she doesn't have her

1:10:09 demand first of all she will answer her question in the paper If I tell you what I will say, then what will you learn in my life? If I tell you what I have given you, I have given you the 50 questions. If you have given you the 30 questions, then what will you learn in my life? If you are going to read, then okay. 32 questions will be the 30 questions. Okay, so I will answer the question. Why do I do a time pass? Why do I do a time pass? Why

1:10:54 do I do a time pass? Can you ask me why? That's why I'm taking the session. What do you want to explain? Let's explain the structure of a chromosome with a diagram. Make a diagram of both of them or make them both. What will we tell about the structure of chromosome? A chromosome is a condensed... chromosome represents the over condensed structure of dna right dna if we over condensation with the help of certain histone and non-histone protein that's what we call chromosome correct first thing second important thing what will you say about chromosome? that chromosome comes

1:11:42 to a small construction We can call it primary constriction This primary constriction is also known as centriole This is called a chromosome This is centriole Or we can call it primary constriction Centromere We can call it a primary constriction On this primary constriction we have a disc like structure A small disc like structure is present which is called kinetochore okay third important is what can we tell about the chromosome? sometimes if we are making this chromosome like gap 1 phase then okay if we talk about the metaphase

1:12:29 chromosome in metaphase chromosome if we talk about the metaphase chromosome shows presence of two chromatids this one and this one which are called sister chromatid If I talk about normal chromosomes, what happens in this? There are two arms present. This is upper arm, this is lower arm. Which you can say P and Q. Now after first or primary constriction, sometimes the chromosomes show presence of another constriction which can be called as secondary constriction. Multiple constrictions are present on chromosome. Now among that secondary constriction 1 What happens in that? It is our nuclear region

1:13:14 organization. Secondary construction 1 represents nucleus. Do you understand? Yes, in this... Nucleolus is called nucleus. Nucleolus is organized here in secondary construction 1. Somewhere here. Do you understand? That is why it is called nuclear organizer region. Correct? And the Secondary constriction 2, where is it? This is our second constriction, the second constriction can also be present. The third constriction can also be present. Sometimes certain chromosomes may show

1:14:04 the presence of the extra lobular part which is called as the satellite body. okay? Tell me this too. Satellite body is also our chromosome. You can see attached to your body. If you know what you can find, you can find the information you can find. What is the question about it? Sex Determination in Honeybee. What does honeybees look like in sex determination? First, tell us about what type is. Deployed type of sex determination Diplontic, especially neat वालो, Haplodeployed, Haplodeployed plant में होता है, Honeybee की बाद चल रही है, Haplodeployed type of sex

1:14:52 determination कहेंगे Honeybee's जो है, इसमें chromosome का number decide करता है जो organism है, उसका gender क्या होगा, correct है तो यहां हम क्या बताआ सकते है कि जो females है females are of two type correct, कौन सी? एक होती है हमारी queen, दूसरी होती है workers among workers, sorry among the female, workers are sterile, they are unable to reproduce और वही queen, queen is alone fertile, correct males are known as drone और drones यह सारे fertile होते है, correct? अच्छा अब हमने haplo deployed type का sex determination बोला, तो इसका मतलब क्या है? जितनी भी females रहेगी

1:15:40 all females are deployed in nature. How many are the 2N numbers? 32. And the amount of males will develop. Males are called drone. How does it happen? It is haploid. If there are 16 number of chromosomes, then it will be a male. If there are 32 chromosomes, then it will be a female. How does this distinction come from queen and worker? Let's talk about it. Let's see what's happening. First, we'll talk about reproduction. Then we'll talk about it. So here, what does this mean? It will be a gametes which we call eggs. We call female produced gametes. Now, brother, we call these gametes. If these eggs are fertilized with the male gametes, if the female

1:16:28 gametes has fertilized, the zygote will be a deployed zygote. It will be a deployed zygote because it is here and here. 2N number is present in it. Correct? So, this is the zygote. zygote will develop that zygote will always develop into the female because female will always be deployed if it is after female fertilization then how does male become? so in honey bee male produce by a process known as parthenogenesis parthenocarpy is a plant in parthenocarpy is associated with female reproductive structure of plant parthenogenesis What happens? Our haploid female meats. They can develop into a complete

1:17:17 organism even without fertilization. So this process is called as Parthenogenesis. Which will be haploid in nature. Now among this diploid zygote, In this case, zygote provides a special type of food which we call royal jelly Royal jelly which is found, that female will develop into the queen Royal jelly which is not found, those female will develop into the workers Correct? Let's go! We have written here, brother! The simple way and simple words, the better way to write it. No difference between the words and the words and words बहुत लंबा लंबा लिख दिया पारग्राफ के पारग्राफ लिख दिया कुछ

1:18:02 नहीं हो रहा हुससे पॉइंट वाइज लिखो चीजों को सिंपल रखो इतना असान रखो अपने पेपर को कि भाई सामने वाला देखते बराबर उसको थोड़ा थोड़ा आइडिया आजा यह Tell me, not

1:18:48 later. I put a pen here. What about that? Explain the process of modification of HNRN into mRNA. If you want to make HNRN from that, then how will it be? You know that this process is happening in eukaryotes. Pro-carriot is not such a problem. So eukaryotes are in 3 steps and we complete the process. Which 3 steps? First splicing, firoga capping and firoga tailing. In splicing what we do? We remove the unwanted region. The things that are called without the work. They are called introns. They are going to fall in the back. So these are introns. They are going to remove the work. which we call axon. This is splicing. Second part is capping. What is capping in capping? Put a cap on some head.

1:19:39 Now our nucleic acid has a head region and it has a tail region. We learn 5 to 3 SI. Where we start, that will be the head region. Put a cap on the head. So who is cap? It is from? hmmm. This is our methyl guanosine triphosphate. Where is the methylated guanosine triphosphate and methyl guanosine triphosphate. Where is the structure? We put it on 5-N. Correct? So that is capping. And the last part is the part. The part is the part of the part. उसमें approximately 2-300 adenylate residues add किये जाते है तो यही

1:20:26 वाला जो पाइट है इसको हम कहते है टेलिंग लंबा सा एक segment उसमें add कर दो पूछ लगा दो भाई आरने को अपने तो यह जो टेलिंग वाला पाइट है जिसमें हमने क्या किया approximately 2-300 adenylate residues add कर दी है और थी डाशेंट इन ही तीन steps के it has been converted to mRNA okay what is the next question? process of DNA replication okay, the question is before this question, in fact, I will tell you, DNA replication can be asked for simple diagram for this diagram only for two marks okay or then can be asked for whole diagram plus

1:21:12 explanation No, I don't have any news about anime. I will talk about you. Just a little while. We will talk about it. We will talk about it. I need to talk about this anime. I will talk about it. But it's not. It's not time for me. We will talk about anime. There is no one in my friend circle. I can discuss it with him. Okay, let's go. So our next question is what is it, Baba? Yes, replication of DNA. Tell me, first we will define DNA replication. What is done in DNA replication? We will make a DNA, two DNA. We will make DNA copy of DNA. That is replication, right?

1:22:03 So when we produce the exact replica or exact copy of DNA, that process is called as DNA replication. You have written so simple definitions, still it is fine. Or if you have to speak very very well, then what is going to be done? Is it or not? If you have written very well, DNA replication is the process. First, you can add some more. In which a DNA molecule makes identical copy of itself. This is also an easy definition. It's not bad enough. Which step is not going to be done. First, initiation. इनिशियेशन में अपना टार्गेट किया है रेप्लिकेशन फोग बनाना रेप्लिकेशन फोग बनाने के लिए सबसे पहले क्या किया जाता है डियन की दोनों स्ट्राइंड को सेपरेट किया जाता है यूजिंग एंजाइम नोनाज हली केज पहले हली केज ने काम किया दोनों

1:23:11 here you can write a point here SSBPs SSBPs are single strand binding proteins prevent rejoining of two strands next we have done this both strands separate, we have to elongate it right so here we will make our hero enzyme that is DNA polymerase first we will put primase what will happen? we will put RNA primer on the 5- end of the DNA template strands correct after addition of RNA primer DNA polymerase will add DNA

1:24:01 nucleotides correct? let me tell you By adenine thymine, I will form a pair of incitocin with a pair of incitocin. Is it correct? Then what will we say? Tell this, don't forget that both strands are made in our DNA. They are made in anti-parallel direction. Right? One strand is produced continuously, that is leading strand. The second strand which is produced discontinuously is called as lagging strand. the smaller fragments on the lagging strand are called as okazaki fragments. Tell me, keep it, tell me, tell me, everything will be elongated and after that we have to terminate the process. So what will we do in termination? We have to join all the okazaki fragments, remove

1:24:49 the primer and add the fragment. So the removal of the RNA primer addition of DNA nucleotide is again done by DNA polymerase and joining of Oka-Zaki fragment is done by ligase. Right? Just finish DNA replication. Tell three points. Initiation, elongation, termination. Okay? Tell me about it inside. Okay. Where will the coal get? The coal will get out of the house. Where will you get the poll? Tell me where you get the poll? You don't have to get it, why did you see MC? You don't see it now?

1:25:37 There's no poll now. It's just your theory question. Okay. This is enough. Yes, Baba, enough. Just join us. Where were you from? After that, Maharaj, your next question. What is Baba? describe various properties of genetic code we will tell you about the genetic code depending on the depending on how much mark is the question we will write our answer for 2 marks, 4 properties, 3 marks, 6 properties or 4 marks, 4 properties, then it will be fine but it will explain it properly so which properties of genetic code

1:26:24 is our genetic code यह ट्रिप्लेट कोड एक लिए कोड करते हैं फिर्स निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइट निग्वाइ that it is non-overlapping non-overlapping meaning that each nucleotide is read only once while translation fourth term is called our genetic code comma less meaning there is

1:27:10 no gap or no pause between two codons what is it? degeneracy what is it? Since there are 61 codons for amino acids and only 20 sorry, since 20 amino acids are coded by 61 different codon, each amino acid may have more than one codon coding for itself. This is called degeneracy. It's complicated to make it more complicated. I have seen the definition here. It will be simple. Many amino acids have multiple codons. Yes, it's done. It's done. It's done in this sentence. Amino acids have multiple codons for them.

1:28:01 That is what degenerates. Okay? Okay. What is the other property? It's explained to someone in a global hypothesis. Okay? It's not universal. Go to any organism. Okay? Every organism, every codon It is the same way, it will not make a metheon in every organism. Okay, non-ambiguous, no confusion. Codons or amino acids will not be confused and doubt. It is the same as the brother said, how do you do it? How do you do it? You shut your eyes and shut your eyes. That's it. This codon has the amino acid, it is the type of property.

1:28:48 after that, there are some special codons, start codons that is AUG, stop codons from UAA, UGA and UAA, UAG, UGA, these are three stop codons, codons and anti codons, where are we? where are we? where are we? where are we? where are we? where are we? where are we? where are we? where define genomics give any two application of genomics, okay? Genomics is what? It is a study of a haploid DNA content of a haploid DNA content. It is called as genomics. study, you know, haploid content of organism is studied under the name of genomics. Write this

1:29:34 down, correct? First thing, please. What is the genomics to analysis sequencing and mapping of gene? They told me a lot about it. What is the genetic material? We are doing sequencing sequencing and then mapping it. What is the gene in which one of the segments is present? So we have done this in genomics. What is the application of this? What is the application of this? we can use in agriculture to develop genetically modified crops first thing because we want to increase the quality of plants and they can transfer superior characters to them

1:30:21 the other thing we can use in forensic science and forensic analysis we can use in medicine medical field to develop certain recombinant routines लाक उपर उपर वैसे सवाल आया नहीं है काफी साल हो गया तो थड़ा सा देख के जाईएगा इसको चैप्टर नेम यह तो मौलीकिलर बेसिस चल रहा है तुम चंदा मत करों मैं तुमको एक वीडियो भेशती हूँ भेशती हूँ भेशती हूँ तो अभी तुरंद में एक द

1:31:10 We will mark it in the text book, but just do it in one session. When will it be done? Katie, it will be 45 minutes. What will we tell about lack operon? Generally, lack operon is a system that represents a cluster of genes present in between single promoter and terminator. If there is multiple proteins

1:32:00 for multiple proteins, it is called an operon system. Lack operon system is present in generally bacteria. which is used for lactose metabolism correct lacoperon is generally turned off in absence of lactose and it is turned on in presence of lactose okay then tell us what is happening when we don't have lactose so somewhere along this genetic material of bacteria there is this repressor gene which we call the i gene what is happening this is our repressor protein form Repressor protein binds to the operator region and the transcription does not take place. This happens in absence of lactose. In presence of lactose,

1:32:46 what will happen? The regulatory gene or I gene will produce repressor molecule. When lactose is present in cell, inducer says here lactose. So lactose binds with the repressor and change its conformation. This structure will change lactose. Now this repressive protein is unable to mind at the operator.
