[@davideisenstadt3745]

Hello NinjaNerd! I think I may have found a discrepancy in this video around 16:20. During the S phase you state that the cell becomes tetraploid (4n) - I believe the cell stays diploid but has 4C (twice the amount of genetic material) after replication.

[@michalzatloukal]

I was thinking the same thing. The number of chromosomes stays the same, but the chromatids of the chromosomes double.

[@holdupaish]

During endoreduplication, the cell replicates its DNA without going through the usual process of mitosis. This results in a tetraploid cell with four sets of chromosomes. During anaphase. In mitosis DNA content is doubled during S phase resulting in 2n chromosomes having two chromatids so, yea

[@thedailydoze8931]

This is the best ever cell cycle class I had... Really I understood concept very well... I can relate you to one my school teacher, who always made her classes interesting...... You are inspiring me to explain all these concepts in Kannada ( my mother toungue - Karnataka, India).... So that many more students, especially the rural students will continue their studies in science stream... Here in India we the students who studies in local language medium will find it hard to study science, as in higher studies they have to suddenly switch to a English medium...when they switch to English medium they find it hard to understand every word and just opt to move away from science stream... ( even I faced such problems )... Hopefully I can help them in future...

Amazing teaching. Thank you for your great work and ad free videos. I'm happy to support you on patreon. Two things: - Personally, I'd move your support call up in your video description so that people can see it without having to click an extra time. - If I'm not mistaken though, you might have used the terminology of chromosomes and chromatids a bit unclearly. During the G1 phase, there are 46 chromosomes with 1 chromatid per chromosome (so 46 chromosomes AND 46 chromatids). And after the S phase, there are 46 chromosomes with 92 chromatids (not 92 chromosomes).

[@TonyTigerTonyTiger]

@@AhmedSalah-sr3os First, complexity is not the sign of a good designer, simplicity is. If you get 20 designers and give them a specification, and all 20 created designs that meet all criteria, the best designer is not the one with the most complex design, but the one with the simplest design. Second, it is a logical fallacy - straw man - to refer to evolution as random knocking at the genetic material. For example, you leave out natural selection, which imposes a directionality onto evolution by tending to eliminate deleterious mutations, and to retain - and spread - beneficial ones.

i dont think it goes from 2n to 4n in mitosis. it stays 46 chromosomes with a diploid number of 2n but it now has sister chromatids. so you have 92 total chromatids. number of chromosomes stays the same in mitosis.

"number of chromosomes stays the same in mitosis." Not after the sister chromatids separate during anaphase and on into telophase, prior to cytokinesis. At that point, the cell is 4n.
