Explanation:
During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.
