During DNA replication, the separation or "unzipping" of the DNA molecule occurs when hydrogen bonds are broken between the nucleobases adenine (A) and thymine (T), as well as between guanine (G) and cytosine (C). These specific base-pair interactions follow the complementary base pairing rules in DNA: A pairs with T, and G pairs with C. Breaking these hydrogen bonds allows the DNA strands to separate, providing templates for the synthesis of new complementary strands during replication.
