How does this apply to epigenetics
WebFeb 26, 2024 · Specifically, epigenetic processes act “upon” the genome, which may open or close the chromatin to various degrees to govern access for reading DNA sequences (Figure 1). When the chromatin is opened, transcription and translation can take place; however, when the chromatin is closed, gene expression is silenced (Syzf et al., 2007). WebFeb 26, 2024 · Epigenetic mechanisms DNA methylation DNA methylation is one of the most studied epigenetic marks and typically occurs at the pyrimidine C5 position of cytosine residues by transferring a methyl group from S -adenosyl- l -methionine (SAM) through the catalytic action of DNA methyltransferases (DNMTs) [ 4, 5, 6 ].
