Question

Which one of the following nucleotide pair bonds would be found in a DNA molecule?
Adenine-guanine b. Guanine-cytosine c. adenine-cytosine d. Cytosine-uracil

Answer 1

Answer:

b

Explanation:

DNA has four nucleobases: adenine, thymine, guanine, and cytosine. The nucleobases in a DNA strand have preferred partners to form hydrogen bonds with. Cytosine pairs with guanine, and adenine pairs with thymine. These are the base pairing rules that allow DNA replication and protein synthesis to happen.
