Quizplus · Accepted Answer

DNA is composed of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases can only pair with one another in a specific way: A can only pair with T, and C can only pair with G. These complementary base pairs allow DNA to make an exact copy of itself during replication, because each strand can be used as a template to produce a new complementary strand with the same base sequence.
