MCAT Modules - Review

End of chapter random info (as I’ve done before). Although pay attention to end where I discuss donor:acceptor ratios of nucleobases.

Discusses why gene expression regulation occurs @ transcription level. Discusses the Jacob Monod Lac Operon’s structure (ZYA) and function (lactose metabolism) and how the repressor (@operator site) controls this process.

LISTEN @ 2x speed (on Apple podcasts). Discusses co- and post-translational modifications (GLUMPP) which occur for those proteins that aren’t fully ready to work even after translation finishes.

Discusses the conservative (Incorrect), dispersive(Incorrect), and Semi-Conservative (Correct) theories of replication.

Discuss endo- and exogenous factors that damage DNA, the process of Nucleotide Excision Repair (NER), and what happens when NER fails.

(This is where the modules get longer/content heavy). Discusses exo- and endonucleases as well as the Mismatch Repair Mechanism as a physiological fail safe.

Strand structure, protection factors (proks have none), and starting A2 (proks = fmet // euks = met)

Discusses the process using the APE Sites.

USELESS MODULE // I didn’t think I’d actually get it to 45 seconds LOL

I know we talked about this in 4:1 but this has more detail. Distinguishes between eukaryotic and prokaryotic transcription and reviews eukaryotic transcription in detail (with processing).
