The most important feature that distinguishes one DNA molecule from another is (are)
A)the type of phosphate bonds.
B)the type of sugar in each molecule.
C)the order of the bases attached to the sugar phosphate backbone.
D)all of the above features

Question

Quizplus · Accepted Answer

The order of the bases attached to the sugar phosphate backbone is the most important feature that distinguishes one DNA molecule from another. This is because the sequence of the four nitrogenous bases (adenine, thymine, guanine, and cytosine) determines the genetic information contained within a DNA molecule. The other features mentioned (phosphate bonds and sugar type) are important components of the DNA molecule but do not contribute to genetic diversity.
