उत्तर
In DNA molecule, pairing between two complementary nucleotides takes place by Hydrogen bonds.
Explanation:
DNA is made of two polynucleotide chains that are antiparallel to each other. Each chain is made of a single monomer nucleotide with sugar and NB bound with Glycosidic bond, which in tum is bound with a phosphate group by an ester bond. Nucleotides are joined to each other by a phosphodiester bond. And the NB pairs are linked by a weak H bonds.
