Question

5. Why are Okazaki fragments formed
on lagging strand only?​

Answer 1

Answer:

Okazaki fragments are formed on the lagging strand so that DNA can be synthesized in the essential 5' to 3' manner on the lagging strand.

Answer 2

Answer:

Okazaki fragments

Okazaki fragments are fragments of DNA that form on the lagging strand so that DNA can be synthesized in a 5' to 3' manner toward the replication fork. If not for Okazaki fragments, only one of the two strands of DNA could be replicated in any organism which would decrease the efficiency of the replication process.
