Study Notes
What is Genetic Engineering?
- The process of manipulating an organism's DNA to introduce new traits or characteristics
- Involves the use of biotechnology to alter an organism's genetic makeup
- Allows for the introduction of desirable traits from one species into another
Types of Genetic Engineering
- Microinjection: injecting genetic material into an organism's cells using a microinjection needle
- Vector-mediated gene transfer: using a vector (e.g. plasmid, virus) to introduce genetic material into an organism's cells
- Biolistics: using a gene gun to shoot genetic material into an organism's cells
- Homologous recombination: using an organism's own genetic machinery to introduce genetic changes
Applications of Genetic Engineering
- Agriculture: developing crops with improved yields, disease resistance, and nutrition
- Medicine: developing new medicines, vaccines, and gene therapies
- Bioremediation: using microorganisms to clean up pollutants in the environment
- Biotechnology: developing new biofuels, bioproducts, and biosensors
Tools and Techniques
- Restriction enzymes: enzymes that cut DNA at specific sequences, allowing for the insertion of new genes
- Ligase: enzyme that seals gaps in DNA, allowing for the formation of recombinant DNA molecules
- Polymerase chain reaction (PCR): amplifying specific DNA sequences for analysis or genetic engineering
- Gel electrophoresis: separating and analyzing DNA molecules based on size and charge
Ethical Considerations
- Safety concerns: unintended consequences of genetic engineering, such as gene flow into wild populations
- Ethical concerns: using genetic engineering for non-therapeutic enhancements, such as athletic or cognitive enhancements
- Intellectual property: ownership and patenting of genetically engineered organisms and genes
- Regulation: government regulations and guidelines for genetic engineering research and applications
Learn about the principles and applications of genetic engineering, including types of genetic engineering, tools and techniques, and ethical considerations. Understand the process of manipulating an organism's DNA and its applications in agriculture, medicine, and biotechnology.
