Describe how the plasmid can be used to genetically modify a bacterial cell to contain a human gene?
Plasmid is cut using restriction enzymes.
Gene is added to plasmid.
Plasmid is inserted into a bacterium.
Suggest the advantages of cloning mammals in use of medical research into human diseases?
Clones are genetically identical so test results will be similar.
Clones could be GE to have human diseases.
