  • genetic engineering and bacteria
    • improving feature of recipient organism
      • inserting gene coding for resistance to herbicide in plants so that farmers can use herbicides
      • interting growth controll gene into livestock to increase muscle production
    • engineering organisms to synthesise useful products
      • goats with silk gene to produce silk milk
      • insulin production by bacteria to be used for humans with diabetes
      • golden rice-introducing beta carotein gene into normal rice crops
        • source of vit a
    • identified gene gut by restriction endonuclease and sealed with DNA ligase
      • vectors are often plasmids-circular DNA
    • Transgenic-organisms that contain DNA from one or more othe organisms from different species
    • plasmids can be swapped between bacterial organisms of different species thus spreading resistance to antibiotics
