10/12/2009 1 C118 Laboratory Genetically Modified Foods A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes. Transgenic organisms, a subset of GMOs, are organisms which have inserted DNA that originated in a different species. Some GMOs contain no DNA from other species and are therefore not transgenic but cisgenic. Have you eaten a genetically modified food? A. Yes B. No C. I’m not sure. Note: all answers will be given credit Rank your level of concern about GM foods in health and the environment . • A. Not at all concerned • B. Somewhat concerned • C. Very concerned • D. Not knowledgeable enough to make a decision

Although not originally developed for the ornamental fish trade, it is the first genetically modified animal to become publicly available as a pet. Normal zebra fish
