Answer: Restriction enzyme
Explanation:
A restriction enzyme can be defined as the enzyme that cleaves The DNA fragments near or at specific recognition site within molecules.
It is one of the class of endonuclease enzymes. EcoRI is an example of restriction endonuclease which is extracted from bacterium E.coli. It recognises 6 nucleotide sequence GAATTC and cleaves between G and A position.
So, the enzyme that is used to cleave genes out of DNA is restriction enzyme.
