In DNA A pairs with T and C pairs with G these are examples of a specific type of reaction called?

In DNA, the pairing of adenine (A) with thymine (T) and cytosine (C) with guanine (G) exemplifies specific base pairing, which is a fundamental aspect of molecular Biology. This type of reaction is facilitated by hydrogen bonding between the complementary bases. The specificity of these pairings is crucial for the structure of the DNA double helix and for accurate DNA replication and transcription.
