Best Answer

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.

It is called a replication fork.

How does topoisomerase affect the DNA strand during DNA replication?

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

Where does replication of the two DNA strands takes place?

in a direction opposite to that of the replication fork

Replication of the two DNA strands takes place?

In the same directions of the replication fork

What does the replication fork do in DNA replication?

Replication forks hold the two separated strands of DNA apart preventing them from assuming their double helic shape.

What are the areas on DNA where replication occurs called?

DNA replication begins in areas of DNA molecules are called origins of replication.

DNA replication that unzip the DNA strand is?

What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.

What happens During replication DNA .?

During DNA replication the following occurs: 1) An enzyme called helicase separates the DNA strands (the space where they separate is called the replication fork). 2) DNA polymerase adds complementary nucleotides to the separated strand of DNA. 3) The DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules.
