Presentation Transcript

  1. You may see this at the supermarket… • What does it mean?

  2. Genetically Modified Organisms Recombinant DNA

  3. Genetically Modified Organism (GMO) • An organism whose genetic material has been altered using genetic engineering techniques.

  4. Genetically modified organisms are used in many foods… • CORNCoca Cola (contains corn syrup)Margarine (corn oil, canola oil)FritosKraft Salad DressingsMcDonalds French FriesNestle CrunchNutra-sweet

  5. More GMOs are being tested… • BarleyBroccoliCarrotsGrapesPeppersRaspberriesStrawberriesSugar CaneWatermelonWheat

  6. Why are GMOs being created? Genes are modified or added to plants… • To make them more resistant to insect pests, weed killers, frost and drought. • Increase the nutrients in a crop or reduce the amount of fertilizer needed. • Corn has been modified so that it produces vaccines for farm animals…

  7. Medical Uses for GMOs Research involving GMOs has produced… • Insulin for diabetes treatment • Treatment for certain cancers • New vaccines • Treatments for genetic disorders such as hemophilia

  8. Transgenic Organisms • GMO that has DNA/genes transferred from another species. • For example: • Bacteria with human genes • Corn with bacterial genes • Tomatoes with fish genes

  9. How are GMOs created? • Enzymes are used to cut DNA into fragments • DNA Fragments are combined to form new plasmids which are inserted into bacteria. • Bacteria reproduce FAST and make many copies of the recombinant plasmid. • Bacteria with recombinant plasmids may express newly added foreign genes…

  10. Fish with bacterial genes…

  11. Are there any risks? • What do you think? • We will examine the potential benefits and risks of GMOs over the next few lessons.
