1.GM needs a DNA vector amd certain enzymes.
vector is the way in which genetic material is transfereed from a donor to a recipient eg, virus, bacteria, plasmids.
2. vectors take pieces of DNA and insert them into other cells, viruses and plasmids can act as vectors.
a virus is an ultramicroscopic infectious non-cellular organism that can replicate inside the cells of living hosts, with negative consequences.
plasmids are the small circular genetic material present in bacterial cells and used in GM.
3. restriction enzymes cut DNA at specific sites, and similarly ligase enzymes join pieces of DNA at specific sites.
restriction enzymes are enzymes that can cut DNA is specific places in the DNA molecule
ligase enzymes are enzymes that can join pieces of DNA together.
