DNA leading strand is constructed through DNA polymerase III whereas Okazaki fragments are constructed through:

Correct answer: B. DNA polymerase III

  • A. DNA polymerase I
  • B. DNA polymerase III
  • C. DNA polymerase II
  • D. DNA Ligase

Explanation

DNA polymerase III is the main replicating enzyme. It has two subunits. Both leading and lagging strands are constructed by DNA polymerase III. Each Okazaki fragment is synthesised by DNA polymerase III in a 5' → 3' direction.
