In a DNA molecule,the base pairs provide information,and the sugar-phosphate backbone does not,because
A)the base pairs are all the same,but the sugar-phosphate backbone varies.
B)there are eight types of base pairs.
C)the bases form a sequence,and the sugar-phosphate backbone does not.
D)the sugar-phosphate backbone is highly unstable.

Question

Quizplus · Accepted Answer

The sequence of the bases in the DNA molecule provides the genetic information. The sugar-phosphate backbone, on the other hand, functions only to provide structural support and stability to the DNA molecule. It does not carry any genetic information, as the order of the sugar and phosphate molecules in the backbone is constant and does not vary.
