Which of the following is a key feature of RNA?
- A. Deoxyribose and thymine
- B. Double stranded and thymine
- C. Ribose and uracil
- D. Ribose and thymine
Explanation
RNA carries ribose, which has a hydroxyl group at carbon 2, and uses uracil in place of thymine, and it is normally single stranded. Deoxyribose and thymine are the DNA features, so options mixing one sugar with the wrong base can be eliminated at once. The extra hydroxyl is also why RNA is chemically less stable than DNA.
