Genetic engineering and recombinant DNA
- Genetic engineering is the deliberate alteration of a genome by substituting or adding genetic material.
- Recombinant DNA combines DNA from two or more sources, such as a plasmid carrying a human gene.
- Bacteria are favoured hosts: they reproduce quickly, are cheap to keep and carry plasmids.
- E. coli carrying the human insulin gene makes human insulin.
