The DNA double helix is stabilized by ________, the interaction between delocalized electrons of aromatic rings in nitrogenous bases.
A) base-stacking
B) dipole-dipole interactions
C) salt bridges
D) hydrogen bonds
E) covalent bonds

Question

Quizplus · Accepted Answer

Base-stacking refers to the stabilizing interactions between the aromatic rings of the nitrogenous bases in DNA, which are a key factor in the stability of the DNA double helix. These interactions involve the delocalized electrons of the aromatic rings, contributing significantly to the overall structure and stability of DNA.

The DNA Double Helix Is Stabilized by ________, the Interaction
