MCQ
Okazaki fragments are synthesised on:
  • A
    Leading strands of DNA only
  • B
    Lagging strands of DNA only
  • C
    Both leading and lagging strands of DNA
  • D
    Complementary DNA

Answer

  1. Lagging strands of DNA only

Explanation:

Synthesis of leading strand DNA, as the name indicates occurs in an easier and faster way in 5' → 3' direction.

Whereas, lagging strand synthesis lags behind and is done with the help of the production of Okazaki fragments in 5' → 3' direction, which are then joined with the help of ligase. This results in the formation of a continuous strand.
