Which statement is true?
a. G-C base pairs have three hydrogen bonds while A-T base pairs have two hydrogen bonds.
b. A-T base pairs have three hydrogen bonds while G-C base pairs have two hydrogen bonds.

Respuesta :

Answer: The correct answer is option A)

G-C base pairs have three hydrogen bonds while A-T base pairs have two hydrogen bonds.

Explanation:

The double helix of DNA is held together by hydrogen bonds between pairs of bases. . Guanine pair with Cytosine base with three hydrogen bonds while Adenine pair with Thymine with two hydrogen bonds.

This makes the base sequence of the DNA complimentary
