Summary Introduction
To review:
The base that will be generated when 5-methylcytosine is hydrolyzed at the 5th carbon of pyrimidine ring.
Introduction:
Methylation refers to the addition of methyl group. In cytosine, methylation takes place at 5th carbon, which results in the production of 5-methylcytosine. This is also known as a methylated form of cytosine, which is a base present in DNA (deoxyribonucleic acid).
