Heterochromatin and Euchromatin
Summary
[edit]
| Description |
English: Histone acetylation or deacetylation alters chromatin structure to create euchromatin or heterochromatin. The dynamic state of histone acetylation/deacetylation is regulated by histone acetyltransferase (HAT) and histone deacetylase (HDAC) enzymes. Acetylation/deacetylation (Ac added to or removed from certain histone tail locations) alters accessibility of chromatin and allows/prevents DNA binding proteins to interact with chromatin to activate or repress gene transcription. |
