WebMar 30, 2024 · The term “epigenetics” encompasses a number of molecular processes including cytosine methylation. Cytosines are typically part of a cytosine-phosphate-guanine dinucleotide site, referred to as CpG sites. These CpG sites can be methylated when a methyl group binds to the cytosine to generate 5-methylcytosine. WebFor example, a chemical reaction called deamination can convert a cytosine base into uracil, a base typically found only in RNA. During DNA replication, uracil will pair with adenine rather than guanine (as it would if the base was still cytosine), so an uncorrected cytosine …
