Chromosomes 

Can't believe it! Your Biology video from 9 years ago is a lifesaver for my upcoming Biotech test next week. Thanks for making learning so engaging!

So much helpful video for every biology students

Thanks! This will definitely help me on my quiz! :)

thanks very good concept i appreciate your knowledge

thank you so much you've helped me a lot

Great video. Very informative.

Great video! I had fun watching this

15:09 hello is the channel still active? I would like to know if it is safe to say that haploid cells are composed of 23 chromatids? not 23 chromosomes? thank you

*8:17** That’s “trisomy 21!*

Wow even if we went 'dirty'😂😂 this video was good. 👍 Thanks for the good explanation and keep it up🙏

very interesting video. ...thank you. ..

7:00 I'm assuming they will have to get chromosomes while a cell is in the process of dividing in contrast to interphase,

Does the XXY chromosome mean a person could be bisexual, homosexual, or transgender?

Thnxx.... it was helpful

Thank you so much ! 🔥

nice one!!!

17:24 "So a zygote marks the beginning of all of our lives." There you have it, pro-choicers. Life begins at conception.

I see this video getting canceled in the near future simply because science is offensive.
