Study Notes
What is Genetic Engineering?
Genetic engineering is the process of altering the DNA of an organism to introduce new traits or characteristics. This is done by manipulating genes, which are the basic units of heredity.
Key Techniques
1. Recombinant DNA Technology
- Involves combining DNA from different sources into a single molecule
- Uses restriction enzymes to cut DNA, and ligases to join DNA fragments
- Creates recombinant DNA molecules that can be introduced into cells
2. Polymerase Chain Reaction (PCR)
- Amplifies specific DNA sequences
- Uses primers to target specific DNA regions, and an enzyme to replicate DNA
3. Gene Cloning
- Creates multiple copies of a gene
- Involves inserting a gene into a plasmid or vector, and introducing it into a host cell
Applications
1. Medicine
- Production of insulin, growth hormone, and other therapeutic proteins
- Gene therapy for genetic disorders
2. Agriculture
- Development of pest-resistant and drought-tolerant crops
- Increased crop yields and nutritional value
3. Biotechnology
- Production of biofuels, bioproducts, and bioremediation agents
- Development of biosensors and diagnostic tools
Ethical Concerns
- Unintended consequences of genetic modifications
- Potential for genetic discrimination
- Patenting and ownership of genetically modified organisms
Safety Considerations
- Containment of genetically modified organisms to prevent environmental release
- Risk of horizontal gene transfer
- Potential for allergic reactions or toxicity
Regulation
- National and international regulations governing genetic engineering
- Guidelines for responsible conduct of genetic engineering research
- Public engagement and participation in decision-making processes
