Cytosin guanin
Guanine (symbol G or 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. The guanine nucleoside is called guanosine. With the formula C5H5N5O, guanine is a derivative of purine, … See more Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. Guanine has two tautomeric forms, the major keto form (see figures) and rare enol form See more The first isolation of guanine was reported in 1844 by the German chemist Julius Bodo Unger [de] (1819–1885), who obtained it as a mineral formed from the excreta of sea … See more Guanine is not synthesized de novo , instead it's split from the more complex molecule, guanosine, by the enzyme guanosine phosphorylase: guanosine + … See more • Cytosine • Guanine deaminase See more Trace amounts of guanine form by the polymerization of ammonium cyanide (NH 4CN).
