Q. This force can stabilize a DNA double-helix
A. Hydrophilic sugar-phosphate groups are found on the exterior of the helix where interaction with water occurs
B. Hydrophobic bases are present in the interior of the helix, each base-pair is stabilized by the same number of hydrogen bonds
C. covalent base stacking interactions may take place between neighbouring bases within the same strand in the helix
D. non-covalent N-glycosidic bonds may form between nitrogenous bases in opposite strands in the helix
Answer: Hydrophilic sugar-phosphate groups are found on the exterior of the helix where interaction with water occurs
