WebDNA methylation is the most common and most stable epigenetic mark. It serves the following functions; The balance between DNA methylation and demethylation determines the access to the DNA during transcription and thus controls gene expression. It one of the important means of regulation of gene expression in eukaryotes. WebDNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription.
