Uracilnoun

(organic compound) One of the bases of RNA, pairing with adenine.

Uracilnoun

a nitrogen-containing base found in RNA (but not in DNA) and derived from pyrimidine; pairs with adenine

Uracil

Uracil (; U) is one of the four nucleobases in the nucleic acid RNA that are represented by the letters A, G, C and U. The others are adenine (A), cytosine (C), and guanine (G). In RNA, uracil binds to adenine via two hydrogen bonds.

Uridinenoun

A nucleoside formed from uracil and ribose.

Uridine

Uridine (symbol U or Urd) is a glycosylated pyrimidine analog containing uracil attached to a ribose ring (or more specifically, a ribofuranose) via a β-N1-glycosidic bond. It is one of the five standard nucleosides which make up nucleic acids, the others being adenosine, thymidine, cytidine and guanosine.
