Unformatted text preview: BIMM100 - Lecture 2 30 Mar MCB 111-126 1 April MCB 126-(139) A Big Day of RNA Key Molecular Processes I (text on reserve@BioMedLib) FAQs next slide Saving paper? Slides 7-12; 14-19 carry over from Lecture 1 (modified order) DNA Supercoiling -- how it happens Alberts 6-20 From Lecture 1: Supercoils build up during processes such as replication and transcription. Would ultimately cause problems if not resolved. TOPOISOMERASES are the enzymes that provide resolution.
