Genetic Modification (genetic Engineering)
Bayani Gaba-gaba
Selective breeding takes generations and is limited to the traits already present in a species. Genetic modification breaks both of those barriers: scientists can now cut a gene from one organism and paste it into an entirely different species, producing a result in months rather than decades.
In this lesson you will learn how restriction enzymes and ligase work together to build recombinant DNA, how plasmids and viruses act as vectors, and how these tools have made it possible to mass-produce human insulin and engineer crops that resist pests and drought.
Manufura
- Understand how restriction enzymes are used to cut DNA at specific sites and ligase enzymes are used to join pieces of DNA together
- Understand how plasmids and viruses can act as vectors, which take up pieces of DNA, and then insert this recombinant DNA into other cells
- Understand how large amounts of human insulin can be manufactured from genetically modified bacteria that are grown in a fermenter
- Understand how genetically modified plants can be used to improve food production
- Understand that the term transgenic means the transfer of genetic material from one species to a different species
