You hear mutations - but we hear variation! Mutations have several causes and can be positive, neutral or negative to the phenotype. Grab a recap of the Central Dogma before diving in (1:40). Distinguish between point mutations and frameshift mutations (2:50). Mutations have a strong correlation to evolution(3:40). Prokaryotes have been around a long time, with many reproductive techniques (5:08). Genotypic changes are also the result of errors in cell division, as with non-disjunction (5:40).
The Question of the Day asks (6:25) “What metal atom is bound to a heme group in hemoglobin?”
