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.
