Cytosine can undergo chemical modifications that play crucial roles in gene regulation and epigenetics. The most common modification is the addition of a methyl group to carbon 5, forming ...

3 Cytosine methylation occurs when a methyl group binds to the fifth carbon of a cytosine to form 5-methylcytosine (5mC). Researchers cannot detect 5mC with traditional molecular techniques such as ...

B) DNA methylation involves conversion of unmethylated cytosine to 5-methyl-cytosine (5mC). A proposed method for DNA demethylation involves sequential oxidation and deamination of 5mC, followed by ...
