20. | Which of the following forces can stabilize a normal DNA double-helix? | |
A. | Base-stacking is a non-covalent interaction that occurs between the relatively hydrophobic bases in the interior of the helix. | |
B. | Base-pairing is a non-covalent interaction that occurs between adjacent bases in the same strand of the DNA molecule. | |
C. | The hydrophilic sugar-phosphate groups are on the exterior of the helix where they can interact with each other. | |
D. | The deoxyribose rings form N-glycosidic bonds with the phosphate groups that link neighboring nucleotides. | |
