To which of the following does guanine form hydrogen bonds in DNA?

To which of the following does guanine form hydrogen bonds in DNA? Correct Answer cytosine

In molecular biology, two nucleotides on opposite complementary DNA strands that are connected via hydrogen bonds are called a base. In the Watson-Crick DNA base pairing, Adenine (A) forms a base pair with Thymine (T) and Guanine (G) forms a base pair with Cytosine (C).
