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
