People having problems with hearing can use wired earphones having equal to or more than 10 mm drivers set to full volume and then listen to his lecture. It worked for me and I used a Boat Rockerz wired bass heads 100, not promoting any brand here but to give an idea about how can you hear his voice properly!
Ppl who r finding it difficult to hear plz use earphones and increase ur volume to maximum. By doing so its much more hearable. Btw nice video, u explained it pretty well...gud job!
Shomu's Biology I have heard that the plant cells have a centrosome is that correct or not if you have an essay or survey of that could you please help me
Yes, it is actually correct, but the centrioles are found only in those eukaryotic plants where flagellate structures are present in the life cycle (many green algae, bryophytes, pteridophytes and cycads). They are absent in angiosperms, higher gymnosperms, some algae and fungi.
Spindle fibres are actually made up of microtubules and a *complete microtubule* is itself made up of *13 protofilaments* of α & β tubulin protein dimers arranged sequentially one below the other. And so texts in the biology books or Zoology books write during cell division, the spindle fibres or the microtubules pull the sister chromatids towards opposite poles.
nice video sir. but in the first part of the lecture it was a bit fast. some things went above my head. i have seen and followed ur other videos very well. those are much more slower and undrstandable. newys thanks for this 👍
No, actually Microtubules grow from the PCM (Pericentriolar material matrix) that he described in the video which acts or behaves as the MTOC ( Microtubules Organising Centre) here.
Correct, there is only a central hub which is rod like protinaceous structure. Due to the absence of any microtubule in the central region, that's why the arrangement is known as (9+0) array!
You are not up to date with microtubule literature. Many concepts that you explained have changed more than a decade ago. For example: 'minus end dissociation' is completely misleading ; dynamic instability ( if that is what you are referring to) happens at the plus end. Infact, minus end is rarely free in nature. Microtubule rescue and catasrophe happens exclusively at the plus end. Refer to in-vitro papers of EB1 to check rates of minus end depolymerization. Whatever you are teaching may be ok with naive students without a research background. But it is hilarious for an active microtubule researcher like me. Please read recent papers to stay up to date. Papers from Eva Nogales lab, Ronald Vale lab and Jonathan Howard lab will be a good starting point for you.
Mayukh guha....so i don't think that botanists come here for understanding the topics ....he is making videos for students who are preparing for entrance exams....
@@akashchauhan430 this topic is important but now if you have question on movement of organelles based on + and - end then students will confuse And I think he should give more information on protein involved in this mitoses process carried by microtubules if he want students to get good or elucidated information
What about other people like south indians who cant understand hindi? Please. People like this sir help us a lot. We are also students. India is a multilingual country. Please remember that.
Triplets don't have 3 tubulins. LOL. Triplets have a complete A 'tubule' and two incomplete (B and C) tubules. Your diagram of a triplet is wrong !! They are not three complete microtubules. Like I said, B and C are incomplete tubules with less number of protofilaments than in A tubule. Also, triplets does not mean three molecules. Are you really calling each microtubule a molecule. Hilarious.
Bro this concept is for the person who is researching... Ik wht r u talking about.. But here sir is discussing this about the students who r taking preparation for entrance... Agar itna kuch bolenge to dimag ke upar se jayega.
Yes, indeed this is correct! The subfibre A towards the inner side is *complete* with *13 protofilaments* and the other *subfibre B and C* are *incomplete* due to sharing of some microfilaments probably 2 to 3 protofilaments common wall. And the three sub-fibres of a triplet fibril named as C, B and A are in reality microtubules joined together by their margin!

sound is very low ...
find difficulty to hear

Thank you.
Problem is here by using earphones too.
Very helpful and awesome teaching style 👍👍👍 you solved all queries related to this topic very nice 👍👍
Thank you so much for appreciating my efforts. Glad to hear that you're getting benefit from my lectures
Shomu sir that 9+2 arrangement is in the flagellum not in the centrosome👍i think
Yes
9plus zero
Yes
9+3
Sir, please let me know the best time to study for final semester exams
Throughout the semester

I have heard that the plant cells have a centrosome is that correct or not if you have an essay or survey of that could you please help me
No bro.. plant cell have polar caps intead of centrosomes
Yes, it is actually correct, but the centrioles are found only in those eukaryotic plants where flagellate structures are present in the life cycle (many green algae, bryophytes, pteridophytes and cycads). They are absent in angiosperms, higher gymnosperms, some algae and fungi.
why they align at an angle of 90°???
then what are spindle fibres? please explain iam confused with microtubules and spindel fibres
Spindle fibres are actually made up of microtubules and a *complete microtubule* is itself made up of *13 protofilaments* of α & β tubulin protein dimers arranged sequentially one below the other. And so texts in the biology books or Zoology books write during cell division, the spindle fibres or the microtubules pull the sister chromatids towards opposite poles.
Your voice is not clear but you explain in very nice way
Thx a lot sir
You are solved my all doubts
You're welcome
Which organism contain centriole throughout the life
nice video sir. but in the first part of the lecture it was a bit fast. some things went above my head. i have seen and followed ur other videos very well. those are much more slower and undrstandable. newys thanks for this 👍
awesome teaching but your voice was so slow can't hear properly

turn it up dawg
Thank you so much
Best explanation ever....
You're welcome. Thank you for appreciating my efforts
You deserve it sir....
Kindly elaborate with the protein involved in this process
Sir how much sub ducts in centriole??
27 or 9????

very helpful video sir😊😊
please make a video on RIBOSOMES
Okay
sir if centrosome are not important and if they are absent then homicrotubules are forme
mitochondria function means i have to write ETC only??
Nice teaching.... But u should increase your voice sir.....
Very nice sir
You're welcome. Glad to hear that you're getting benefit from my lectures
Awsm video👌👌👌
In which phase or interphase centrosome devides...

can u plz attach a collar mike as ur voice is v low in all videos despite of putting headphones
Sir plzz try to speak loudly...
U r teaching very best..
But due to ur low sound it is not easy to listen u...
It's recorded in low volume
In which phase of interphase centrioles are duplicated
S or in some cases G2 phases
How microtubule grow in centrosome? only grow from centriole?
No, actually Microtubules grow from the PCM (Pericentriolar material matrix) that he described in the video which acts or behaves as the MTOC ( Microtubules Organising Centre) here.
Voice is too loud 🔊. Glasses of my spectacles shattered.
shit you right my g
Awesome 🙏
Thank you
Can u explain this subject more please?
Sir voice clear nahi aa rahi
hit like if you like his videos even without watching.....
Super bayyaaa thanq
Thanks sir
You're welcome
plz tell me how to concntrate in my studies
Please provide this in hindi
Hi guys people who are finding difficulty in the sound, can use earphones, maybe it will work.
Thank you
1 centrosome contains 2 centrioles?

Yes
Explaination is nice but voice is so low
