Question 12 • First Semester Biology

Which statement describes one way that RNA differs from DNA?

Answer
A
One is a protein, and the other is a nucleic acid.
B
They contain different five-carbon sugars and a different nitrogenous base.
C
They are both carbohydrates, but one is a polysaccharide.
D
One provides energy, and the other carries genetic information.

Explanation

RNA contains the five-carbon sugar ribose, while DNA contains deoxyribose. They also differ in one nitrogenous base: RNA uses uracil, while DNA uses thymine. Thus, choice B correctly identifies two ways they differ.
