Quizplus · Accepted Answer

In a double-helical DNA, adenine (A) pairs with thymine (T) through two hydrogen bonds, and guanine (G) pairs with cytosine (C) through three hydrogen bonds. Therefore, the statement that wherever there is an adenine on one strand of a helix, there must be a thymine on the other strand, is true.
