Final answer:
Complementarity is the term that describes how the sequence of one DNA strand specifies the sequence of the other, with base pairs A-T and C-G during DNA replication.
Step-by-step explanation:
The term that refers to the fact that the sequence of one DNA strand specifies the sequence of the other strand in the double helix is complementarity. In DNA, the two strands are complementary because of the base pairing rules, where adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, if one strand has a sequence of AGTCATGA, its complementary strand will have the sequence TCAGTACT. During DNA replication, the two strands of the double helix separate, and each strand serves as a template for creating a new complementary strand.
