A purine that is one of the five main bases found in nucleic acids Guanine base pairs with cytosine
One of the four types of nitrogenous bases found in DNA, having the double-ring structure of a class known as purines Guanine always forms complementary base pairing with a DNA pyrimidine base called cytosine Guanine also occurs in RNA molecules Back to Homepage H h
Organic compound of the purine family, often called a base, consisting of two rings, each containing both nitrogen and carbon atoms, and an amino group. It occurs in combined form in many important biological molecules, particularly nucleic acids, and free or combined in various natural sources, including guano, sugar beets, yeast, and fish scales. In DNA its complementary base is cytosine. It or its corresponding nucleoside or nucleotide may be prepared from nucleic acids by selective techniques of hydrolysis
