- Genetic modification is where a gene from one organism is transferred to another
-The stages of Genetic Modification
-First the gene that's responsible for producing the desirable protien is isolated, its position on the source DNA is identified
-The useful gene is then replicated to create lots of copies.
-Each gene is joined to a vector, a carrier for the gene which makes it easier to insert into a new cell. Plasmids and viruses are often used as vectors
