Watched your video (twice) and now I finally get it, I can finally move on, and because of this comment section I can thank finally thank you! So again thank you so much for what you do. You're one of the best!

I just wanted to let you know that you do an amazing job at explaining biology clearly or in a way that is easy to understand. Keep making videos. I really appreciate them. It is hard to understand when my professor lectures because he makes everything seem so complicated. He even puts up lecture videos just like you, but when I do not understand him, which is often, I come to your videos. Please continue to do what you do. It makes my class easier and my grade higher.

@rasmasyean 9 жыл бұрын

Chanelle Nique That's because this video is oversimplified. For example, not all genes code for proteins. Some just code for RNA molecules (different classes too), etc. Also he's missing a Histone (which all the other histones are wound over. I'm not sure if this is simplified for HS students or that his biology is outdated, but no college professor would simplify it to this level.

@calebhaines3794 3 жыл бұрын

So quantum base pairs would allow regulatory strands to turn on and turn of genes in a different order because quantum genes will interact with the world differently , they will have to be activated in such a way that anatomical cells can carry out human DNA instructions in a more efficient manner. This requires predictive modeling and accurate placement of quantum material so that genes are sustainable and will produce new cells that contain quantum precise proccesses.
