Two potential functions that eukaryotic cells perform to regulate transcription are DNA methylation: a process of epigenetics that participates in the regulation of the gene expression in two ways, directly impeding the union of the transcription factors, and indirectly propitiating the closed structure of the chromatin, and Histone acetylation, enzymes that acetylate conserved lysine residues in histones by transferring an acetyl group from an acetyl-CoA molecule, to form ε-N-acetyl lysine, is extensively associated with an open chromatin structure and therefore accessible to transcription factors, which increases gene expression.
Two Potenital Function
Following are the two potential functions that eukaryotic cells perform to regulate transcription as:
- DNA Methylation
- Histone Acetylation
DNA methylation is a method through which methyl groups are combined with the DNA molecule. Methylation can alter the action of a DNA segment without adjusting the sequence. When positioned in a gene promoter then DNA methylation typically serves to repress gene transcription.
Histone acetylation is the method through which the lysine deposits in the N-terminal tail projecting from the histone core of the nucleosome are acetylated as a role of gene regulation. Histone acetylation is necessary parts of gene regulation.
