how are enzymes used in genetic engineering
The term vector means any organism that will carry the gene from one place to another. The most common vector used in genetic engineering is a circular form of DNA known as a plasmid. Endonucleases are used to cut the plasmid molecule open at almost any point chosen by the scientist.Once the plasmid has been cut open, it is mixed with the insulin gene and a ligase enzyme.he term vector means any organism that will carry the gene from one place to another.
