Replication forks hold the two separated strands of DNA apart preventing them from assuming their double helic shape.
The topoisomerase enzyme uncoils the double helical structure of DNA during its replication to form the replication fork. In eukaryotes both posive and negative supercoils get unbind by topoisomerase I & II respectively.Topoisomerase isomerase unwinds DNA to form replication fork
What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.

1. Helicases unwind the double helix at the replication fork and single strand binding proteins (SSBs) stablilize unwound DNA ahead of the fork.
replication fork
That would be called the Replication Fork
The DNA replication fork is where the replication origin forms the Y shape. The replication fork moves down the DNA strand to the strand's end, resulting in every replication fork having a twin.
Both occur at the Replication Fork. Don't let the name deceive you.

It is called a replication fork.
The topoisomerase enzyme uncoils the double helical structure of DNA during its replication to form the replication fork. In eukaryotes both posive and negative supercoils get unbind by topoisomerase I & II respectively.Topoisomerase isomerase unwinds DNA to form replication fork
in a direction opposite to that of the replication fork
In the same directions of the replication fork
DNA replication begins in areas of DNA molecules are called origins of replication.
