Answer:
In DNA molecules, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). These base pairings are essential for the structure and replication of DNA. Adenine and thymine form two hydrogen bonds between them, while guanine and cytosine form three hydrogen bonds. These base pairings ensure the complementary and accurate replication of DNA during cell division.
