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. WebIn simple terms, hydrogen bonding is the formation of hydrogen bonds. It mainly occurs between an electronegative and a hydrogen atom. Some of the common electronegative atoms are fluorine, chlorine, and oxygen. Compared to the covalent or ionic bond, the hydrogen bond is generally weaker. However, it is stronger than the van der Waals forces.
