Uracil. There are five bases in RNA/DNA. They are Adenine, Thymine, Guanine, Cytosine and Uracil. In DNA: Adenine pairs with Thymine, and Guanine pairs with Cytosine In R â¦ NA: Adenine pairs with Uracil and Guanine pairs with Cytosine. + 10 others found this useful.
Uracil is found in RNA and binds to adenine via 2 hydrogen bonds, but is replaced by thymine in DNA. Methylation of Uracil produces thymine. Uracil can pair with any of the base pairs depending on arrangement. Despite this, it readily pairs with adenine because the methyl group is repelled into a fixed position. In the uracil and adenine bond, uracil is the hydrogen bond acceptor and the adenine is the donor. When attached to a ribose sugar, the compound is called uridine, a nucleoside. Then, phosphate attaches to uridine to form uridine 5'-monophosphate.
