  • Gene therapy
    • SOMATIC CELL GENE THERAPY
      • adding genes
        • faulty alleles are replaced by functioning gene(s) that can then produce correct polypeptides.
      • killing specific cells
        • using genetic techniques to make cancerous cells express the gene for cell surface antigens so that the immune system will recognise and destroy them
    • GERMLINE CELL GENE THERAPY
      • uses early embryo stem cells before specialisation can occur
      • every cell in the grown organism contains a copy of the engineered gene
      • can be passed on to offspring
      • illegal and unethical
    • used to treat genetic disorders
