  • 3. 1. What is a transgenic food?
    • A genetically modified organism is characterized by contain a fraction of the DNA from another agency integrated into their own DNA. In other words, the GMO presents a new piece of DNA that distinguishes it from its conventional counterpart.
  • 4. 2. Historical Background
    • Towards 11000 a.C. men primitive "tamed" the first plant variety for food.
    • In 6000 a.C. manufacturing the beer in Mesopotamia
    • 15TH century the first peppers similar size pepper grain achievement of successive selections of the best seed be increased the size.
    • 19TH century Pasteur enunciates the theory of biological fermentation
  • 5.
    • Mendel makes all tests on the transmission of characters in the peas
  • 6. 3. What is genetic information?
    • ORGANISM DNA GENE
    • their characteristics are is stored in the Strech of DNA that
    • determined by genetics nucleus of her cells determined the chara-
    • cteristics of the body
  • 7. 4.How is made ?
    • DNA extracted from an organism
    • A nother body, is extracted protein gene we want to implement
    • the transgene with the genetic information if implanted in organism that we can change his characteristics.
    • Genetically engineered cloned, modified, and gene fragments
    • DNA is introduced to the tomato without damaging the cell.
  • 8.  
  • 9. 5. FIRST MARKETING
    • May 18, 1994 when the Food and Drugs (DEA) of E. E. U. U. authorize the marketing of the first food with a gene "strange“. Flavr Svr . This tomato had beenmodified to resist any longer after ripening.
  • 10. 6. How are GM foods?
    • Nowadays we currently serve only a few genetically modified vegetables
    • Another major product is the GM soy. In this case, what has beendone is to introduce a gene that makes it resistant to a herbicide.
  • 11. How are GM foods?
    • Transgenic maize has been obtained to be resistant to an insect,the corn borer and herbicide.
    • The prospects of this technology are vast. and there are severaldozen more plants close to the market, and in the coming years thenumber will rise to hundreds.
  • 12.  
  • 13. 7. Goals
    • It`s herbicide-tolerant
    • Transgenic Food disease-resistant caused by a virus, bacteria and fungi.
    • Transgenic Food cold-resistant.
    • You can get varieties of transgenic plants in need minus water.
    • . This could help combat undernourishment in developing countries of the third world.
  • 14. 8. Public risks of transgenic food
    • Emergence of antibiotic resistance in bacteria pathogenic to humans.
    • Genetic contamination isirreversible and unpredictable.
    • endangered species and varieties traditionally grown.
    • Emergence of new allergies by introducing new proteins in food.
    • Increased food contamination by greater use of chemicals in agriculture.
  • 15. 9. Ignorance
    • The spanish people is fed a lot of transgenics without know it.
    • Nor do we know if a lot of mealt, milk or eggs from animals fed transgenic feed,  only label and is not required to label the finished products.
    • Corn, soybeans or their industrial derivatives are present in more than 60 percent of processed foods, from chocolate to potato chips, to margarine and foods.
