This force can stabilize a DNA double-helix

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
