Answer

Complementary bases in DNA are held together by hydrogen bonds. Aadenine (A) forms two hydrogen bonds with thymine (T), and cytosine (C) forms three hydrogen bonds with guanine (G). These hydrogen bonds create stable pairs between the nitrogenous bases, contributing to the structural framework of the DNA double helix.
