Quizplus · Accepted Answer

Okazaki fragment A is the shortest and closest to the replication origin, indicating that it was synthesized earliest. Okazaki fragments are synthesized in a discontinuous manner with the lagging strand, starting at the replication origin and moving away from it. Therefore, the fragments synthesized later will be progressively longer and farther from the origin.
