Euchromatin facultative expression
WebEuchromatin - active gene expression; loosely packed chromatin. Facultative - middle man between euchromatin and constitutive. Has some HP1 protein and methyl groups. Constitutive - has heterochromatin 1 protein (HP1) and other repressive modifications that makes chromatin very tightly packed. WebA. Epigenetic changes are transmissible from cell to cell B.

WebHeterochromatin is a constituent of eukaryotic genomes with functions spanning from gene expression silencing to constraining DNA … Euchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription. Euchromatin stands in contrast to heterochromatin, which is tightly packed and less accessible for transcription. 92% of the human genome is euchromatic.
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 …
