DNA and RNA are chiral molecules in nature, their chirality is due to

Options

  1. AL-sugar component
  2. BD-sugar component
  3. Cchiral phosphate ester units
  4. Dchiral bases

Correct answer

B. D-sugar component

Step-by-step solution

The constituents of nucleic acids are nitrogenous bases, sugar and phosphoric acid. The sugar present in DNA is D(-)-2-deoxyribose and the sugar present in RNA is D(-) ribose. Due to these D(-)-sugar components, DNA and RNA molecules are chiral molecules in nature.
