Question

What are Okazaki fragments and how they are formed?

Short answer

Small pieces of DNA known as Okazaki fragments are created during DNA replication's discontinuous synthesis of the lagging strand.

Step-by-step solution

Introduction 

The small DNA nucleotide sequences are known as Okazaki fragments. In order to create the lagging strand during DNA replication, they are intermittently produced and then further linked by the ligase enzyme.

The explanation for the answer. 

Okazaki fragments are produced on lagging strands as a result of the primosome producing a fresh RNA primer. For the purpose of synthesising DNA in a 5′ to 3′ direction toward the replication fork, Okazaki fragments are produced on the lagging strand.
