Question

Quizplus · Accepted Answer

Hydrogen bonds form between the partially positive hydrogen on the guanine and a more electronegative nitrogen on the cytosine. There are two hydrogen bonds formed between the base pair A-T and three hydrogen bonds formed between the base pair G-C. Therefore, the correct answer is D, which indicates that two hydrogen bonds form between a guanine and a cytosine.
