4.4 discuss the implications of the use of genetically modified organisms on humans and the environment
Medical
- human growth hormone
- vaccines - eg for influenza
- factor VIII - a blood clotting protein
- insulin production
4.3 discuss the benefits and hazards of gene therapy
gene therapy is the treatment of a disease by manipulating the genes in the person's cell
Cystic Fibrosis (CF) is a genetic disease in which abnormally think mucus is produced in the lungs and other parts of the body. The person will be prone to bacterial infection because mucus cannot be removed so bacteria can breed in it.
4.2 explain the steps involved in recombinant DNA technology
- the plasmid is isolated and taken from the bacterium
- DNA making up the plasmid is cut using restriction enzyme
- Insulin gene is isolated and cut using same restriction enzyme
4.1 outline the principles of restriction enzyme use in removing sections of the genome
Genetic engineering is using technology to change the genetic material of an organism.
Recombinant DNA is a DNA that has had DNA from a different species inserted into it.
