Methyltransferase complexed with DNA, molecular model. The strand of DNA (deoxyribonucleic acid, red and green) is enclosed by DNA methyltransferase 1 (DNMT-1, brown). This enzyme acts to add methyl groups to the DNA, a process called DNA methylation, which can silence and regulate genes without changing the actual genetic sequence. DNA methylation is also being studied in relation to cancer.
