The way in which DNA methylation is related to cancer. Introduction: The alteration to the structure of chromatin affects the gene expression which is known as epigenetic changes. These changes are considered to be the major reason behind cancer. The change in the structure of the protein which is related to transcription is DNA methylation. The methylation of base cytosine resulting in 5-methylcytosine that causes repression of transcription. Methylation helps in removing acetyl group present in the histone tails and stabilizes and represses transcription.
