Which nitrogenous bases pair together in DNA replication?

In DNA replication, the nitrogenous bases pair according to base-pairing rules: 1) Adenine (A) pairs with Thymine (T), and 2) Cytosine (C) pairs with Guanine (G). These pairings are stabilized by hydrogen bonds: A forms two hydrogen bonds with T, while C forms three hydrogen bonds with G. These specific base pairs are essential for maintaining the integrity of the genetic code during replication, ensuring that the new DNA strands are complementary to the original strands.
