Study Notes
- Genetic engineering involves the manipulation of recombinant DNA from two or more species to create genetically modified organisms (GMOs)
- Recombinant DNA is the basis for genetic engineering and can be transferred into organisms using vectors like plasmids, bacterial artificial chromosomes, yeast artificial chromosomes, or viruses
- Genetic engineering process starts with isolating and cloning required genes using polymerase chain reaction (PCR)
- Genes are then inserted into the host genome by cutting both the isolated gene and vector using restriction enzymes and ligating them together
- Transgenic organisms have DNA from a different species incorporated into their genome, while GMOs have their DNA altered but not necessarily from another species
- Examples of genetic engineering include BT cotton, a GMO and transgenic organism that produces a bacterial toxin as an insecticide, and golden rice, a GMO that produces beta carotene for increased nutritional value
- Genetic engineering has played a significant role in agriculture, medicine, and research with the production of human insulin, Interferon for viral treatments, and gene function studies, respectively.
