Unlike DNA, a molecule of RNA contains
- A. ribose and uracil
- B. deoxyribose and thymine
- C. ribose and thymine
- D. deoxyribose and uracil
Explanation
RNA has the sugar ribose and uses uracil in place of thymine, pairing uracil with adenine. DNA keeps deoxyribose and thymine, and the two features always travel together as a pair when the two nucleic acids are compared.
