  • Q:

    DNA strands with higher percentages of G and C nucleotides have higher melting temperatures than strands with higher percentages of A and T nucleotides. This is because:

     

    A

    G and C nucleotides form covalent bonds while A and T nucleotides form hydrogen bonds.

    B

    G and C nucleotides are smaller and thus more closely packed together.

    C

    G and C nucleotides form 3 hydrogen bonds while A and T nucleotides form only two.

    D

    G and C nucleotides are larger and thus have higher boiling points.
