Solution

Feature Leading Strand Lagging Strand
1. Direction of synthesis Synthesized continuously in the same direction as the replication fork. Synthesized discontinuously in the opposite direction of the replication fork.
2. Formation Formed as a single, continuous strand. Formed in short fragments called Okazaki fragments.
3. Requirement of primers Requires only one RNA primer to start synthesis. Requires multiple RNA primers, one for each Okazaki fragment.
4. DNA polymerase movement Moves toward the replication fork. Moves away from the replication fork.
5. Speed of synthesis Faster because it is continuous. Slower because it is discontinuous.
