Uracil vs. Thymine

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.

Thyminenoun

A heterocyclic base, 5-methylpyrimidine-2,4(1H,3H)-dione; it pairs with adenine in DNA.

Thyminenoun

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

Thymine

Thymine (T, Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase.
