Which statement about nonpolar interactions in the formation of the DNA double helix is INCORRECT?
A. Van der Waals interactions are nearly optimal in a double-helical structure.
B. Nonpolar surfaces of the bases are moved into contact with each other due to a more complete base stacking.
C. Nucleotide bases tend to stack even in single-stranded DNA molecules.
D. The separation distance of the planes of adjacent bases needs to be adjusted for the favorable van der Waals contacts.
E. Surface complementary maximizes the formation of hydrogen bonds and van der Waals interactions while minimizing the nonpolar surface area exposed to the aqueous environment.
