Deoxyguanosine (short dG or DNA sequences only G ) is a nucleoside and consists of the nucleobase guanine and sugar β- D -Desoxyribose .

Deoxyguanosine is part of deoxyribonucleic acid (DNA) and forms a base pair with deoxycytidine . The analog with ribose is guanosine .

Structural formula of a GC base pair

It can also form the structure of G-quadruplexes , which is particularly important for telomeres . Four dG lie in one plane and are connected via hydrogen bonds .
