Adenine vs. Guanine

Adeninenoun

A base, C5H5N5, found in certain glands and tissues, which pairs with thymine in DNA and uracil in RNA.

Adeninenoun

(biochemistry) purine base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA

Adenine

Adenine (A, Ade) is a nucleobase (a purine derivative). It is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The three others are guanine, cytosine and thymine.

Guaninenoun

(chemistry) A substance first obtained from guano; it is a nucleic base and pairs with cytosine in DNA and RNA (by means of three hydrogen bonds).

Guaninenoun

a purine base found in DNA and RNA; pairs with cytosine

Guanine

Guanine (; or G, Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA). In DNA, guanine is paired with cytosine.
