What's the difference between RNA and DNA?

Options

  1. ABase
  2. BSugar
  3. CSugar and base
  4. DPhosphate

Correct answer

C. Sugar and base

Step-by-step solution

DNA has deoxy ribose pentose sugar and four nitrogenous bases i.e. adenine [A], guanine [G], both are purines and cytosine [ C ] , thymine [ T ] are pyrimidines. While RNA has ribose pentose sugar and four nitrogenous bases as in DNA except uracil [U] in place of thymine.
