Question

Quizplus · Accepted Answer

DNA does not contain equal amounts of adenine (A), thymine (T), guanine (G), and cytosine (C) on a molar basis. The amounts of A and T are equal, and the amounts of G and C are equal, but the ratio of (A+T) to (G+C) can vary among different organisms or different DNA molecules.
