  1. Technology of Engineering Food

  2. The common between... flounder tomato Tomato has an engineered gene from the flounder  Antifreezing gene

  3. Survey • What is biotechnology? - What is DNA? - What kind of mechanisms do exist? - What is the best method?

  4. Biotechnology • -What is Biotechnology? • What is DNA? • What kind of mechanisms do exist? • What is the best method?

  5. What is Biotechnology? • What is DNA? • What kind of mechanisms do exist? • What is the best method? DNA Shortening of: deoxiribonucleic acid -Segments of DNA are called genes -Four bases (Guanin, Cytosin, Adenin, Thymin) -Bases are connect with sugar and phosphat Double-helix-structure (like a spiral staircase)

  6. Mechanisms • What is Biotechnology? • - What is DNA? • - What kind of mechanisms do • exist? • What is the best method? Biologically Mechanically Vector: Bacterium Injection Biolistic Vector: Virus Protoplast Transformation

  7. Agrobacterium Tumefaciens

  8. Virus

  9. Protoplast Transformation - Taking a cell from an organism • Dissolving of the cellwall by enzymes •  Protoplast is left over - Adding the new DNA • Cellwall has to recover in a growth media

  10. Injection Injecting new DNA with a needle into the nucleus of a cell.

  11. Biolistic • Small beads coated with DNA are load in a gene gun. • Shooting the ball into the cell nucleus • It cuts the DNA section of the cell and „glues“ the desired DNA into it.

  12. Marker Genes • To find out if the transformation has been succesfull • scientists intodruce a marker gene to the host. • Cells which have been transformed will grow in a media while the other cells will die.

  13. Best Method • What is Biotechnology? • - What is DNA? • What kind of mechanisms do exist? • What is the best method?

  14. Isn´t it fantastic what the scientists can do with their technology?

  15. But what will the future bring? Do scientists know their limits?
