WebGene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA.

WebApr 8, 2024 · Euchromatin is a form of chromatin that is lightly packed—as opposed to heterochromatin, which is densely packed. The presence of euchromatin usually reflects that cells are transcriptionally active, i.e. they are actively transcribing DNA to mRNA. Euchromatin is found in the nucleus of eukaryotes and represents more than 90% of the … WebAll three domains of life use positive regulation (turning on gene expression), negative regulation (turning off gene expression), and co-regulation (turning multiple genes on or off together) to control gene expression, but there are some differences in the specifics of how these jobs are carried out between prokaryotes and eukaryotes.
