WebMar 1, 2024 · Transcriptionally active chromatin, as well as RNA-binding proteins, can be found in these RNA-rich regions. Euchromatin resembles an amphiphile-stabilized microemulsion These observations are... WebHeterochromatin is defined as the enormously stained region of the chromosomes with DNA-specific strains and is relatively condensed. They are the firmly packed form of DNA in the nucleus. The structuring of heterochromatin is so highly compact that these are very hard to get access to the protein which is engaged in gene expression.
WebJan 29, 2024 · Chromatin architecture plays major roles in gene regulation as well as in the repair of DNA damaged by endogenous or exogenous factors, such as after radiation. Opening up the chromatin might provide the necessary accessibility for the recruitment and binding of repair factors, thus facilitating timely and correct repair. The observed … Webeuchromatin: [noun] the part of chromatin that is genetically active and is largely composed of genes.
