Study Notes
- Biotechnology is the manipulation of organisms or their components to produce commercial products via genetic engineering.
- The first utilization of microbes in biotechnology was in bread making using airborne wild yeast around 4000 BC.
- Traditional biotechnology involves using natural organisms to create or modify foods intentionally or other useful products.
- Modern technology is the deliberate manipulation of an organism’s genes to change or improve for human use.
- Gene splicing is a process where DNA is cut from an organism and a gene from another organism is inserted, creating recombinant DNA.
- Gene splicing can allow single-celled organisms to produce useful products like human insulin.
- Uses can include production of genetically modified organisms (GMO), forensic techniques or parentage testing.
- DNA profiling determines the specific characteristics of an individual's DNA.
- DNA barcoding is used to identify a species instead of an individual.
- Transgenesis is genetic modification with the assistance of a virus, plasmid, or gene gun via direct injection of DNA.
- Transgenesis must be done in the embryonic stage or in the egg.
- Transgenic organisms can pass modifications to future generations by breeding within the same species.
- In vitro refers to processes done "outside" the body.
- Bioremediation is the use of organisms to control pollution.
- Bioleaching is a bioleaching process used in the mining industry.
- In transgenic plants, antisense genes are used to silence other genes.
- Luciferase (luciferin) is also used in transgenic plants.
- Transgenic animals involve microinjecting foreign genes directly into eggs, whether in vitro or in vivo.
- Xenotransplantation involves genetically modifying animals to provide organs suitable and safe for transplantation into humans.
