Advances in 21st century research and genetic engineering have made it possible to create new genetically modified organisms (GMO). This new technique of manipulating genetic material is known as recombinant DNA technology. In a biotech lab, a molecular biologist (Science Investigator) selects specific genetic information that will either be added to an organisms DNA and/ or knocked out of the DNA. An organism that has newly inserted DNA, or genetic material removed and/ or replaced, is called transgenic.
Many of the mice, rats, monkeys, and other animals used in scientific research are transgenic species. This multi-lesson unit will follow a transgenic mouse’s tale from genetic manipulation, to the birth of founder mice, lab research, then ultimately to the end and sacrifice of the animal for scientific research.
