EPIGENETIC EFFECTS
A. Epigenetic Effects that Involve Chromatin:
- Most phenotypic changes
- Epigenetic effects =
- Still a self perpetuating condition =
1. Methylation effects:
- Covalent
- Occurs as
- One allele un-methylated =
- Other allele methylated =
- When methylated allele becomes
replicated,
- Have two alleles of identical DNA
sequence,
2
2. Heterochromatin affects
- Proteinaceous structures
- Example =
