Which enzymes are required to produce human proteins, using genetic modification?

20.3.1 Define genetic engineering as changing the genetic material of an organism by removing, changing or inserting individual genes

20.3.2 State examples of genetic engineering: – the insertion of human genes into bacteria to produce human insulin – the insertion of genes into crop plants to confer resistance to herbicides – the insertion of genes into crop plants to confer resistance to insect pests – the insertion of genes into crop plants to provide additional vitamins

20.3.3 Outline genetic engineering using bacterial production of a human protein as an example
