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