- Watch this short NOVA video on this form of control of gene expression that is heritable, affects phenotype, but does not alter the sequence of bases in DNA.
- Read chapter 12 through page 401.
- Be prepared answer the following questions in class on Tuesday:
- What is monoallelic expression?
- Identify as true or false the following statements:
- "epigenetic changes that take place during cell differentiation are normally erased in the germline."
- "there are examples in both plants and mammals of epigenetic variants that are transmitted through meiosis."
- Describe (very briefly!) the major type of DNA modification that occurs in most animals and plants.
- Describe the connection between this epigenetic modification, euchromatin, and heterochromatin.
- Indicate what epigenetic change marks genes for silencing.
- Identify histone modifications that are also epigenetic signals.
- Describe (very briefly) "genomic imprinting."
