| Name: |
5-Methylcytosine |

| Description: | 5-Methylcytosine is a methylated form of cytosine in which a methyl group is attached to carbon 5, altering its structure without altering its base-pairing properties. 5-Methylcytosine is an epigenetic modification formed by the action of DNA methyltransferases. Its function varies significantly among species. In bacteria, 5-methylcytosine can be found at a variety of sites, and is often used as a marker to protect DNA from being cut by native methylation-sensitive restriction enzymes. (Wikipedia) |
