What is True about DNA methylation and explain in detail?
DNA methylation is an epigenetic mechanism used by cells to control gene expression. A number of mechanisms exist to control gene expression in eukaryotes, but DNA methylation is a commonly used epigenetic signaling tool that can fix genes in the "off" position.Methylation epigenetically modifies the function of the DNA.
