The hydrophobicity of the planar nitrogenous ring structures of a nucleotide, leading to the exclusion of water and stability of DNA, is referred to as:
A)Watson-Crick base pairing.
B)supercoiling.
C)base-stacking interactions.
D)complementarity.
E)polarity.

Question

Quizplus · Accepted Answer

The hydrophobicity of the planar nitrogenous ring structures of a nucleotide is due to the stacking interactions between them. These interactions lead to the exclusion of water and contribute to the stability of DNA. Watson-Crick base pairing, supercoiling, complementarity, and polarity are not directly related to the hydrophobicity of the planar nitrogenous rings in DNA.
