- Sainmhíniú Guanine is one of the five main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, thymine, and uracil. Guanine is paired with cytosine to form the base pair G-C (guanine-cytosine) in the DNA. The other base pair in the DNA is A-T (adenine-thymine). It is a derivative of purine, consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds.

- Nóta In 1656 in Paris, François Jaquin (a rosary maker) extracted from scales of some fishes the so-called pearl essence, crystalline guanine forming G-quadruplexes. The first isolation of guanine was reported in 1844 from the excreta of sea birds, known as guano, which was used as a source of fertilizer. The guanine nucleoside is called guanosine.

- Sainmhíniú """La guanine est une base azotée, et plus exactement une base purique. On la trouve sous forme de nucléotide : dans l'ADN c'est la dGMP pour désoxyguanosine monophosphate, et dans l'ARN la GMP pour guanosine monophosphate. La guanine s'apparie avec la cytosine dans l'ADN comme dans l'ARN.""" Tagairt "Wikipédia, L'encyclopédie libre, http://fr.wikipedia.org/wiki/Guanine [14.2.2007]"
