Dna Technology

  1. 2. Genetic Engineering and Recombinant DNA Technology
  2. 9. Transgenic Plant
  3. 10. Transgenic Papaya <ul><li>A gene from the virus which encodes a protein in the virus’ outer coat is copied into the plant’s DNA. The plants then makes the coat protein, which is harmless, but which stimulates the plant’s natural defenses. </li></ul><ul><li>Recently, cultivated Hawaiian papayas were hit by a devastating virus which essentially eradicated the commercial variety. Only the transgenic papayas survived. If you like papaya, you can only buy the transgenic variety. Nobody can grow any other kind. </li></ul>
  4. 11. <ul><li>Transgenic mice with human growth hormone </li></ul><ul><li>Transgenic Mice that glow in the dark – asthma research </li></ul>
  5. 12. <ul><li>Zebra fish that glow in the dark – a sea coral gene is placed in the fish </li></ul><ul><li>Transgenic goats engineered to produce antithrombin protein in their milk – for people that have rare blood clotting disorders </li></ul>
  6. 13. The Benefits of Genetic Engineering <ul><li>Human Insulin </li></ul><ul><li>Crops with herbicide resistance </li></ul><ul><li>Crops with virus resistance </li></ul><ul><li>Crops that are drought tolerant </li></ul><ul><li>Control the ripening of fruits </li></ul><ul><li>Crops with increased nutrition </li></ul><ul><li>Milk production in cows </li></ul>
  7. 14. <ul><li>What are the potential problems with genetic engineering? </li></ul><ul><li>People have concerns…Why? </li></ul>
