When found as the second base in a codon, the third is always interchangeable. Find out more about the company LUMITOS and our team. Active enzymatic deamination of cytosine or 5-methylcytosine by the APOBEC family of cytosine deaminases could have both beneficial and detrimental implications on various cellular processes as well as on organismal evolution. Cytosine can also be methylated into 5-methylcytosine by an enzyme called DNA methyltransferase or be methylated and hydroxylated to make 5-hydroxymethylcytosine. This preview shows page 4 - 8 out of 8 pages. Cytosine has not been found in meteorites, which suggests the first strands of RNA and DNA had to look elsewhere to obtain this building block.
