Noun
a base found in DNA (but not in RNA) and derived from pyrimidine; pairs with adenine
Source: WordNetAdenine pairs with thymine (two hydrogen bonds), and guanine pairs with cytosine (stronger: three hydrogen bonds). Source: Internet
Adenine binds with thymine and uracil; Thymine binds only with adenine; and cytosine and guanine can bind only with one another. Source: Internet
At these points, one primer set recognizes DNA with cytosines to amplify methylated DNA, and one set recognizes DNA with uracil or thymine to amplify unmethylated DNA. Source: Internet
DNA is first treated with sodium bisulfite, which converts unmethylated cytosine bases to uracil, which is recognized by PCR primers as thymine. Source: Internet

Here, purines form hydrogen bonds to pyrimidines, with adenine bonding only to thymine in two hydrogen bonds, and cytosine bonding only to guanine in three hydrogen bonds. Source: Internet
