Answer:
Tow replication forks form a lagging and leading strand.
Explanation:
During the process of DNA replication, there forms a Y shaped junction called replication fork. At each replication origin, two replication forks are formed in opposite polarities.
At one replication fork, a discontinuous stand is formed called lagging strand, and at the other replication fork, there forms a continuous strand in 5' to 3' direction called leading strand.
