Unlike DNA, a molecule of RNA contains
Correct answer: A. ribose and uracil
- 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.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
