@Leesarani.

DNA methylation means the addition of methyl group.

Srejan said:   7 years ago
DNA 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. DNA methylation typically acts to repress gene transcription.
