WebEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single carbon-nitrogen ring. flying to usa rulesWebDec 21, 2024 · The nucleotides forming each DNA strand are connected by noncovalent bonds, called hydrogen bonds.
