Genetically Modified Organisms
Transcript of Genetically Modified Organisms
Groups such as Greenpeace and Council of Canadians argue about the lack of long term studies History of GMOs 1900: European plant scientists began using Gregor Mendel's genetic theory to manipulate plant species 1953: James Watson and Francis Crick discover the three-dimensional double helix structure of DNA. This discovery led to other methods of genetic modification; such as splicing. 1973: creation of the first successful recombinant DNA organism. 1980: U.S. Supreme Court allows the use and marketing of GMOs. This decision allows GMO's such as Oil eating micro organisms to be created. 1982: U.S. Food and Drug Administration approves the first genetically modified drug. The drug creates a bacteria that produces an insulin very similar to human insulin 1986 & 1987: first field tests of genetically modified plants and crops are done. The first genetically modified vaccine for humans was created. A genetically modified mouse became the first GM mammal 1992: FDA states that GMOs are "not inherently dangerous" and Product regulation is not needed. A GM Tomato that was created to have a longer shelf life was approved for commercial use, 2000: 130 countries agree to the use and marketing of GMOs. Two new sheep (Cupid and Diana) are created by cloning. This time, scientists are able to not just transfer genes but limit other genes How GMOS are Negatively Affecting us (continued.) 1997: A sheep named dolly was cloned. There were many failures in the process of this cloning because many of the clones were born with severe illness'. Finally a successful clone was created, but it died at the age of 6. Increased vitamin and minerals. Important vitamins such as vitamin A or vitamin C can be increased. Lack of vitamin A can increase blindness. thousands go blind in africa every year. GMO's can decrease this rate.
