  • Gene Therapy
    • Altering  alleles to cure genetic disorders
      • Recessive
        • Add a  working dominant allele
      • Dominant
        • 'Silence' it so allele doesn't work anymore
    • Alleles inserted using 'vectors' (vehicles for alleles)
      • Different vectors
        • Altered viruses
        • Plasmids (rings of bacterial DNA)
        • Liposomes (spheres of lipids)
    • Somatic
      • Body cells
        • e.g. epithelial cells lining the lungs (because CF causes respiritory problems)
    • Germ  line
      • Sex cells
        • Every cell of offspring will be affected by therapy (Won't have the disease)
        • Illegal in humans
