D2.2.7 (HL)—Epigenetic inheritance Topic Practice
D2.2.7 (HL)—Epigenetic inheritance Topic Practice
Students practise evaluating evidence for transgenerational epigenetic inheritance through DNA methylation or histone modification persistence.
How this is tested
- apply knowledge of DNA methylation stability across mitosis or meiosis to explain inheritance of silenced gene
- interpret experimental data showing identical DNA sequences but differing gene expression in offspring linked
