Sugar moiety in DNA and RNA molecules respectively are

Options

  1. Aβ - D - 2 - deoxyribose, β - D - deoxyribose
  2. Bβ - D - ribose, β - D - 2 deoxyribose
  3. Cβ - D - 2 - deoxyribose, β - D - ribose
  4. Dβ - D deoxyribose, β - D - 2 deoxyribose

Correct answer

C. β - D - 2 - deoxyribose, β - D - ribose

Step-by-step solution

Deoxyribo nucleic acid or DNA contains 2 -deoxy- D -ribose sugar unit, whereas ribo nucleic acid or RNA contains D -ribose sugar unit. β - D - 2 deoxyribose in DNA β - D -ribose in RNA
