Cytosine

Cytosine is a pyrimidine base. It forms complementary base pairs with the purine guanine (Cay-34248) in DNA and RNA and is a precursor of uracil (Cay-26088). Methylation of cytosine is a key epigenetic mark that plays a role in gene regulation.Formal Name: 6-amino-2(1H)-pyrimidinone. CAS Number: 71-30-7. Synonyms: 4-Aminouracil, NSC 27787.
