G.M FOOD

  1. 1. GENETICALLY MODIFIED ORGANISM
  2. 2. INDEX <ul><li>1. What is a transgenic food? </li></ul><ul><li>2. Historical Background </li></ul><ul><li>3. What is genetic information? </li></ul><ul><li>4. How is made ? </li></ul><ul><li>5. First marketing </li></ul><ul><li>6. How are GM foods? </li></ul><ul><li>7. Goals </li></ul><ul><li>8. Public risks </li></ul><ul><li>9. Ignorancia </li></ul>
  3. 3. 1. What is a transgenic food? <ul><li>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. </li></ul>
  4. 4. 2. Historical Background <ul><li>Towards 11000 a.C. men primitive &quot;tamed&quot; the first plant variety for food. </li></ul><ul><li>In 6000 a.C. manufacturing the beer in Mesopotamia </li></ul><ul><li>15TH century the first peppers similar size pepper grain achievement of successive selections of the best seed be increased the size. </li></ul><ul><li>19TH century Pasteur enunciates the theory of biological fermentation </li></ul>
  5. 5. <ul><li>Mendel makes all tests on the transmission of characters in the peas </li></ul>
  6. 6. 3. What is genetic information? <ul><li>ORGANISM DNA GENE </li></ul><ul><li>their characteristics are is stored in the Strech of DNA that </li></ul><ul><li>determined by genetics nucleus of her cells determined the chara- </li></ul><ul><li>cteristics of the body </li></ul>
  7. 7. 4.How is made ? <ul><li>DNA extracted from an organism </li></ul><ul><li>A nother body, is extracted protein gene we want to implement </li></ul><ul><li>the transgene with the genetic information if implanted in organism that we can change his characteristics. </li></ul><ul><li>Genetically engineered cloned, modified, and gene fragments </li></ul><ul><li>DNA is introduced to the tomato without damaging the cell. </li></ul>
  8. 9. 5. FIRST MARKETING <ul><li>May 18, 1994 when the Food and Drugs (DEA) of E. E. U. U. authorize the marketing of the first food with a gene &quot;strange“. Flavr Svr . This tomato had beenmodified to resist any longer after ripening. </li></ul>
  9. 10. 6. How are GM foods? <ul><li>Nowadays we currently serve only a few genetically modified vegetables </li></ul><ul><li>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. </li></ul>
  10. 11. How are GM foods? <ul><li>Transgenic maize has been obtained to be resistant to an insect,the corn borer and herbicide. </li></ul><ul><li>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. </li></ul>
  11. 13. 7. Goals <ul><li>It`s herbicide-tolerant </li></ul><ul><li>Transgenic Food disease-resistant caused by a virus, bacteria and fungi. </li></ul><ul><li>Transgenic Food cold-resistant. </li></ul><ul><li>You can get varieties of transgenic plants in need minus water. </li></ul><ul><li>. This could help combat undernourishment in developing countries of the third world. </li></ul>
  12. 14. 8. Public risks of transgenic food <ul><li>Emergence of antibiotic resistance in bacteria pathogenic to humans. </li></ul><ul><li>Genetic contamination isirreversible and unpredictable. </li></ul><ul><li>endangered species and varieties traditionally grown. </li></ul><ul><li>Emergence of new allergies by introducing new proteins in food. </li></ul><ul><li>Increased food contamination by greater use of chemicals in agriculture. </li></ul>
  13. 15. 9. Ignorance <ul><li>The spanish people is fed a lot of transgenics without know it. </li></ul><ul><li>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. </li></ul><ul><li>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. </li></ul>
