- Genetic modification
- Restriction enzymes
- DNA cutting enzymes
- Ligase
- Joins broken molecules of DNA together
- Plasmid
- A plasmid is a small circle of DNA
- Vector
- A vector is an organism that does not cause disease itself
- For example plasmids and vectors
- Vectors take up pieces of DNA, then insert the recombinant DNA into other cells
- A vector is an organism that does not cause disease itself
- Recombinant DNA
- DNA that has been formed artificially by combining DNA from different species
- Human insulin
- 1) The gene for making insulin is cut from a length of human DNA using restriction enzymes
- 2) It is inserted into a plasmid using ligase enzymes
- 3) The plasmid goes into a bacterial cell
- 4) The transgenic bacterium reproduces, resulting in millions of identical bacteria that produce human insulin
- Food production
- Increased resistance to a range of pests and pathogens
- Increased heat and drought tolerance
- Increased salt tolerance
- A better balance of proteins, carbohydrates, lipids, vitamins and minerals
- Transgenic
- Transgenic means the transfer of genetic material from one species toanother
- they contain genes transferred from another species.
