The animation I watched was about a p53 molecule. It is a molecule protein which binds to specific sequences next to the genes which it controls. There is a p53 molecule binding to its binding site. It recruits a RNA polymerase which is an enzyme that makes a new RNa strand using a DNA template. p53 molecule initiates the transcription of mRNA. It relates to the course, because we just had an exam on DNA transcription.
