D2.2.4 (HL)—Epigenesis Topic Practice
D2.2.4 (HL)—Epigenesis Topic Practice
Students practise distinguishing epigenesis from genetic change by analysing how differentiation emerges without DNA sequence alteration.
How this is tested
- explain how epigenetic mechanisms establish cell-type-specific gene expression patterns during embryonic
- contrast epigenesis with mutation by referencing unchanged DNA sequence alongside heritable changes
