The complementary base pairing of DNA allows for precise replication because each base (A, T, C, G) pairs specifically with its complementary base (T, A, G, C) in a predictable manner. This means that when the two strands of DNA separate to allow for replication, each strand can serve as a template for the creation of a new complementary strand, resulting in two identical copies of DNA.
