Topic 7.3 - Genetic Manipulation

  • Modern cloning techniques include:
    • Tissue Culture: using small groups ofncells from parts of a plant
    • Embryo Transplants: splitting apart cells from a developing animal embryo before they become specialised, then implanting the identical ebryos into host mothers
    • Adult Cell Cloning: 
      • the nucleus is removed from an unfertilised egg cell
      • the nucleus from an adult body cell is removed from it's cell and inserted into the egg
      • an electric shock then acts as a catalyst for the egg cell to begin to divide to form embryo cells
        • These embryo cells contain the same genetic information as from the adult body cell
      • When the embryo has developed into a ball…
