@aaishakhanniazi8984 5 лет назад

Centrosomes are microtubule organizing centres and essentially the spot where centrioles are. Centrioles, nobody knows what they do

@mathu991 5 лет назад

A bound pair of centrioles make up a centrosome. The centrioles are the cylinders made up of 9 triplets of microtubules.

Khan academy, I have followed your videos for about a year now and it has helped me so much. I have a first year BSc undergrad exam in a few days and your teaching is the best by far. You've got it spot on. Amazing! Thank you for your help. I'm confident of passing (touch wood). You correct your mistakes as you go showing how easy it is to do, you use simplistic language, its easy to the eye and ear and I think some people like to have a moan for moan's sake.

During your first overview of the difference between mitosis and meiosis (during approx. 2:35) shouldn't in Meiosis ,after the M1 stage, there be two diploid cells? These two diploid cells would then split to haploid cells? thanks, -kid attempting to pass his test tomorrow

This was a well done explanation of the phases of meiosis, but the speaker sounds a bit confused and doing so you confused me on some of the parts as well such the explanation of the "Interphase" the speaker drew the chromosome in the shape it would potentially be in the "Prophase1".The speaker should have explaining as it is.
