During replication, you must find the complementary DNA strand that matches.
In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine (A) always pairs with (T) thymine, and (G) guanine always pairs with (C)cytosine.
