- A Continuously in the same direction as the replication fork movement
- B Discontinuously, away from the replication fork, in short fragments
- C Without any RNA primer
- D In the 3 prime to 5 prime direction by DNA polymerase
Correct answer: B. Discontinuously, away from the replication fork, in short fragments
Explanation: Because DNA polymerase synthesises only 5 prime to 3 prime, the lagging strand is made discontinuously in short Okazaki fragments moving away from the fork.
