What accounts for the stability of the DNA molecule?
A) The bonds between purines and pyrimidines
B) Phosphodiester bonds between the nitrogenous bases
C) Strong hydrogen bonds between the sugar and phosphate groups

Question

Quizplus · Accepted Answer

The stability of the DNA molecule is primarily due to the hydrogen bonds between complementary purines and pyrimidines (adenine with thymine and guanine with cytosine) and the stacking interactions between the base pairs.
