Did you know?
WebOne mechanism of epigenetic modification is DNA methylation. DNA methylation is the process of adding a methyl group to a cytosine base in the DNA strand, via covalent bond. This process is carried out by specific enzymes. [3] These methyl additions can be reversed in a process known as demethylation. WebJan 22, 2024 · Epigenetic modifications include DNA methylation, histone modifications, and non-coding RNAs. At present, more than 100 kinds of modifications have been described, including methylation, acetylation, phosphorylation, sumoylation, ubiquitylation, citrullination, biotinylation, crotonylation, and ADP ribosylation.
