Study Notes
Genetic Engineering Overview
- Genetic engineering is the direct manipulation of an organism's DNA to alter its characteristics.
- It enables scientists to introduce new traits into an organism, improving or creating desired functions.
Methods of Obtaining New DNA
- Transformation: The process of introducing foreign DNA into a host organism's cells, often using plasmids.
- Transfection: A technique that involves the insertion of nucleic acids into cells, usually using chemical, physical, or viral methods.
Recombinant DNA Milestone
- The first recombinant DNA molecule was created by Herbert Boyer and Stanley Cohen in 1973.
- They utilized a plasmid to combine DNA from two different species, paving the way for genetic engineering research.
Purpose of Gene Insertion
- Inserting genes aims to enhance or modify an organism's traits, such as improving crop yield, disease resistance, or producing pharmaceuticals.
- This technique also allows for the study of gene function and regulation.
Term for Genetically Engineered Organisms
- An organism generated through genetic engineering is known as a genetically modified organism (GMO).
- GMOs are often used in agriculture, research, and medicine to produce desired traits or substances.
