I am a tutor in physiology, physics, chemistry, and mathematics, and I must say you have a very special way of breaking down the information in a comprehensible, sequential manner that is just really enjoyable to hear and watch. You are definitely helping a lot of people with your linear, step-by-step methods. I've always been fond of cell signaling pathways and understanding them from start to finish. Very well organized!

THANK YOOOOOOU. I looked everywhere for a decent video that explains this stuff! This video is clean and not a jumbled and crazy. PLEASE DONT STOP MAKING VIDEOS THEY'RE TOO GOOD!

You need an award, sir! You are really helping me out understanding this on a basic level!

I've been struggling in class to understand the checkpoints and have had no luck in finding videos that explain how it works. I greatly appreciate your help and finally have a sense as to what is going on!

This is what I always want from a discussion, there are always new trivias/facts added and goes beyond the surface of the lesson (defining terms, explaining what is already in the ppt, and whatnot).

Your videos are incredible and break down the most complex concepts into a step-by-step, comprehensive way. You are absolutely saving me in my biology course! Thank you!

Professor Dave is lit af man. I look at this channel for all my college classes. The way he explains is extraordinary.

Nicely explained Dave sir! You deserve more subscribers. I hope you will get at least 10M subscribers. Love from India

An excellent tutor with an excellent explaining skills. Thank you very much indeed for your tutorial videos Professor Dave!

You are fantastic! As simple as that! I can always go watch your videos, when I need 'the quick and dirty' version of a whole semester, I struggled understanding! And then so many things fall into place! Thank you Dave!

Your method of teaching and breaking down concepts is absolutely remarkable. I am a chemistry teacher and my school required me to teach biology and learning from your videos has literally taught me the whole course in a few simple videos😅. Remarkable explanation. Please keep up the good work.

Well done Dave, this is a great presentation

This is remarkably impressive... Prof Dave, you have a unique talent of deconstructing complex subjects. WOW!

Video saved for my upcoming January exam!! Love you.

This is indredibly great explained. Thank you so much!

Good tutorial as always, Dave!

This helped a little on the subject, thanks. I even learned some extra information!

its reassuring to see that the numbers in my textbook line up perfectly with the examples you give. you are quite literally on the same page.

I am astonished by how you explained it so well. Well done...

Quick question- Chromosomes can be monads (a single chromatid) or dyads (sister chromatids held together by a centromere; a dyad has two identical strands of DNA held closely together in a location called the centromere). When a cell is in the G1 or Gap 1 Phase of their cell cycle, the nucleus contains monads but during the S phase the DNA is synthesized into the dyads that are seen in the G2 or Gap 2 phase. *The strands are identical assuming that no copying errors (mutations) have occurred during the S phase of the cell cycle Familiarize yourself with the conditions of a cell’s chromosomes during the G1 and G2 phases of the cell cycle. The 4 phases of mitosis: Prophase = chromosomes condense Metaphase = chromosomes line up in the middle of the cell with reference to the two poles (the equatorial plate or metaphase plate) with each chromosome on its own spindle fiber (by itself) Anaphase = separation of the chromosomes Telophase = formation of two nuclear envelopes around the two chromosomal clusters and then the cell divides (cytokinesis) Questions: In humans, there are 46 chromosomes in the nucleus of a cell. When the cells are in the G1 phase the 46 chromosomes are 46 monads which are 46 single chromatids. During the S Phase the 46 monads become 46 dyads which are 46 sister chromatids that will split during the M Phase/Mitosis. What is in the nucleus of the cell after mitosis?

this is great video! really helped me understanding cell cycle regulation! thanks!

This was great. So simplified!! Thanks.

you are saving my life right now thank youuuu

Very nice job Prof Dave!

I’m a first year student of molecular biology! Thank you professor 👨‍🏫

Thank you so much for this informative video

Man , that was well expained. Thank you!

Amazing explanation thank you 🙂

Man I gotta love that iconic intro

Thank you brother Dave!

Thank you so much for this....now clearly understood...I can now prepare my presentation☺️...God bless🙏

Well explained, understandable and clear... Thank you prof. All your videos are very useful. I've been watching all of them.

Thank you ...well explained.

It's well explained. Thank u

Thank you so much for excellent explanation

This is so helpful!! Thank youu

In school, we watch the explanation videos. At home, I watch the debate videos.

@dave So Cyclins and kinases provide the signal to help the cell move along through the checkpoints...but how do they know the cells are "fit" to continue forward to the next phase.

thank you biology jesus

Please make videos with more explanation ....request. Your videos are best .

İ wish to have you in my collage dude, i didn't just learn, i enjoyed it

Thanks . It helped me a lot.

thank you professor dave

great video really helpful thanks a lot

perfect!!! sugestion: video about mosaicism

one quick question dave. if nerve cells don't divide at all like you said, then how can doctors treat brain cancer? bcs, once the doctors get rid the tumor cells within the brain, don't they wait for certain amount of times so that the cells he cut form the new one. thanks

OMG THIS IS SO HELPFUL 🌺🌺🌺

Do cells grow during the g0 phase?

Wow! This is great continent! Simple and accurate! Just consider revising your explanation on chromatin structure...As far as I know chromosomes only go supercoiled for cell division...the DNA is largely in a "loose" state for replication and storage... otherwise it couldn't be used. (I'm not considering heterochromatin here, of course) Anyhow, great video!! :)

Todd pls!

Hey Todd!! aha come on phagocyte! - haha I need to talk to people, I've been studying too long

hi taylor

1:03 Why are they called daughter cells? And not son cells, for example?

@AnushkaSharma-ok2er

3 жыл бұрын

we call it daughter cell since only *female* can reproduce.. so as it will grow it will become a mother cell and divide further.

something about chemical signaling, they must remain in the G0 state!

after studying biology in depth for many years I have slowly but surely started believing in a higher power. And after further research I have decided that there can only be 1 God responsible for the intricacy of the human body.

@@WokeandProud I do not understand what you mean by "taking it too far" secondly, things like emergence personally are not strong enough evidence to compensate for the incredible intricacy of the Universe and human physiology.
