AP Bio: Molecular Genetics - Part 1

[@robertlyons8154]

This has helped me with an extremely difficult AP Biology class where the teacher doesn't do much lecturing and it is a lot of taking notes at home. Thank you. This is truly making a difference.

Your sense of humor makes this fun to watch lol

[@liltyo4342]

Good job. I. Am currently in ap bio, and the book can be quite overwhelming with its massive amounts of text and high vocab. You restated the book in easier terms, and did a good job explaining.

This might be personal, but do you support the harming of mice for experimental purposes? I don't.

thanks mate

[@mohamadaminyarahmadi9794]

but I didn't understand last slide

[@ScienceWithJohnston]

Basically you have some heavy old DNA, and as you copy that DNA to reproduce the DNA copies made with only light "new" DNA nucleotides were half heavy, and half light. This supported semiconservative replication where when copied DNA has one :old" strand and one "new" strand built to complement the nucleotides on the old one. That's my quick attempt I can manage tonight if it helped.
