In a DNA molecule: drugs or polypeptides may bind at either the major groove or the minor groove. there are three hydrogen bonds between guanine and cytosine, but only two between adenine and thymine. nucleosides outnumber nucleotides. there are two hydrogen bonds between guanine and cytosine, but three between adenine and thymine.

there are three hydrogen bonds between guanine and cytosine, but only two between adenine and thymine.

Explanation:

This is the only true statement, thanks to these hydrogen bridges that allow the interaction of the nitrogen bases and the formation of the double helix.

-Drugs or polypeptides may bind at either the major groove or the minor groove. This is a false statement because the DNA is made of units called nucleotides.

-nucleosides outnumber nucleotides: the nucleotide number is equal to that of nucleotides, because the nucleoside is the part of the nucleotide corresponding to the sugars + nitrogenous base

- there are two hydrogen bonds between guanine and cytosine, but three between adenine and thymine. False because there are three hydrogen bonds between guanine and cytosine, but only two between adenine and thymine.
