What enzyme is used to copy a pice of DNA

The enzyme in charge of this is called a helicase (because it unwinds the helix). The point where the double helix is opened up and the DNA is copied is called a replication fork. Once the strands are separated, an enzyme called DNA polymerase copies each strand using the base-pairing rule.

Explanation:

The point where the double helix is opened up and the DNA is copied is called a replication fork. Once the strands are separated, an enzyme called DNA polymerase copies each strand using the base-pairing rule.There are two types of gene cloning: in vivo, which involves the use of restriction enzymes and ligases using vectors and cloning the fragments into host cells (as can be seen in the image above). The other type is in vitro which is using the polymerase chain reaction (PCR) method to create copies of fragments of DNA.
