Answer :
Final answer:
The components of replicating DNA strands include Parental DNA, DNA polymerase, leading strand, lagging strand, DNA ligase, and replication fork.
Explanation:
The components of replicating DNA strands include:
- Parental DNA, which serves as the template for the new DNA strands.
- DNA polymerase is an enzyme that adds nucleotides to the growing DNA strand.
- The leading strand is synthesized continuously in the direction of the replication fork, while the lagging strand is synthesized discontinuously in the opposite direction.
- DNA ligase joins the Okazaki fragments of the lagging strand.
- Finally, the replication fork is the structure where DNA replication occurs.

A DNA fork is a structure that forms during DNA replication. The double helix structure of DNA needs to be unwound in order for replication to occur. The labeled diagram is attached below.
What is a replication fork?
This unwinding takes place at a specific point on the DNA molecule called the replication fork. The replication fork is formed by the separation of the two complementary strands of the DNA double helix, and it acts as a template for the synthesis of new DNA strands. The replication fork is maintained by enzymes called helicases, which unwind the DNA, and primases, which add short RNA primers to the template strands. The process of replication continues as the two strands of DNA are separated and new nucleotides are added to each strand by DNA polymerase.
