WebFacultative heterochromatin. Facultative heterochromatin is a dynamic structure that can convert between the heterochromatin and euchromatin states. For example, when one of the two X chromosomes in female mammals is chosen to be inactivated during early embryogenesis, the X chromosome is converted from euchromatin to heterochromatin … WebSep 26, 2024 · Euchromatin is a kind of chromatin that is lightly packed (DNA, RNA, and protein) and is abundant in genes.

WebHeterochromatin is a functionally distinct genomic compartment that is characterized by its relatively low gene density, enrichment for repetitive sequences and transposable elements, highly compact chromatin architecture, and late onset of DNA replication.
