RNA differs from DNA in
A) its single-stranded nature.
B) the type of sugar found in the nucleotide.
C) the types of pyrimidine bases.
D) the type of sugar found in the nucleotide, the types of pyrimidine bases, and its single-stranded nature.
E) the types of pyrimidine bases and its single-stranded nature only.

Question

Quizplus · Accepted Answer

RNA differs from DNA in three ways: its single-stranded nature, the type of sugar found in the nucleotide (ribose instead of deoxyribose), and the types of pyrimidine bases (uracil instead of thymine). Therefore, choice D is correct as it includes all three differences. Choices A and E are incorrect as they only list one or two of the differences. Choice B is incorrect as both DNA and RNA contain sugars, but they differ in the type of sugar. Choice C is incorrect as both DNA and RNA contain pyrimidine bases, but they differ in the types of pyrimidine bases.
