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

Options

  1. AChiral bases
  2. BChiral phospbate ester units
  3. CD-sugar component
  4. DL-sugar component

Correct answer

C. 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.
