In DNA, the complimentary bases are

Options

  1. AAdenine and thymine; guanine and cytosine
  2. BAdenine and thymine; guanine and uracil
  3. CAdenine and guanine, thymine and cytosine
  4. DUracil and adenine; cytosine and guanine

Correct answer

A. Adenine and thymine; guanine and cytosine

Step-by-step solution

Deoxyribonucleic acid (DNA) has the purine bases adenine and guanine and pyrimidine bases thymine and uracil According to base pairing rule adenine paired with thymine (A=T)(A=T) and cytosine paired with guanine (C≡G)(\mathrm{C} \equiv \mathrm{G}).
