How does the sugar in DNA differ from the sugar in RNA?

Options

  1. ADNA sugar is alpha-D-ribose, while RNA sugar is beta-D-ribose.
  2. BDNA sugar is beta-D-ribose, while RNA sugar is alpha-D-ribose.
  3. CDNA sugar is alpha-D-2-deoxyribose, while RNA sugar is beta-D-ribose.
  4. DDNA sugar is beta-D-2-deoxyribose, while RNA sugar is alpha-D-2-deoxyribose.

Correct answer

D. DNA sugar is beta-D-2-deoxyribose, while RNA sugar is alpha-D-2-deoxyribose.

Step-by-step solution

The sugar in DNA is beta-D-2-deoxyribose, while the sugar in RNA is alpha-D-ribose.
