Guanine

Guanine is a purine base. It forms complementary base pairs with the pyrimidine cytosine in DNA and RNA. Guanine can be linked to ribose via a beta-N9-glycosidic bond to form the purine nucleoside guanosine (Cay-27702), which can be phosphorylated to guanine-based purines that have numerous roles in intracellular signal transduction.Formal Name: 2-amino-1,9-dihydro-6H-purin-6-one.
