Adenine

Adenine

Adenine is one of the precursors of DNA and RNA nucleotides along with Cytosine, Guanine, Thymine, and Uracil. It is a purine nitrogenous base that consists of fused 5- and 6-member rings of Carbon and Nitrogen atoms. In DNA, the complementary base pair of Adenine is Thymine, while Uracil pairs with Adenine in RNA. Atoms shown: Carbon (black), Nitrogen (green) and Hydrogen (red) [LM] {GE} {RH}
