Saturday Aug 31, 2024
Saturday Aug 31, 2024
Here we survey of the causes and consequences of genetic mutation, including a discussion of mechanisms of endogenous and induced mutations, rates of mutation, types of single nucleotide mutations, and the phenotypic effects of mutation. We also discuss various mechanisms for detecting and repairing genetic mutations, including base excision repair, DNA mismatch repair, nucleotide excision repair, double strand break repair. We conclude with an examination of large-scale chromosomal changes, including deletions, duplications, inversions, and translocations, unequal crossing over, with a brief look at polypoidy in plants and aneuploidy in humans. Recommended pre-listening is Episodes 34 and 35: DNA Structure and Function, and Episode 44: Cell Division.

I like listening to stuff like this he talks away too fast for my brain to actually absorb 100%. But I never got anything but a high school education and I wished I had a better IQ to have gotten into science. I understand it it’s the thing is I forget what I learned.
