2. Gene Therapy is a technique for correcting defective genes responsible for disease development Gene Therapy is a technique for correcting defective genes responsible for disease development Gene therapy is the process of introducing a new gene into a cell in order to replace one that isnt functioning correctly Gene therapy is the process of introducing a new gene into a cell in order to replace one that isnt functioning correctly

3. Monoclonal antibodies Hybridomas made of monoclonal antibodies and transformed cancer cells Hybridomas made of monoclonal antibodies and transformed cancer cells Attack malignant specific tumor cells and prevent tumor growth by targeting specific cell receptors Attack malignant specific tumor cells and prevent tumor growth by targeting specific cell receptors Gene therapy can deliver these antibodies to specific tumor cells Gene therapy can deliver these antibodies to specific tumor cells

8. Enzyme Replacement Therapy The human body utilizes enzymes to digest food and carry out vital activities for normal life function The human body utilizes enzymes to digest food and carry out vital activities for normal life function Replacing an enzyme in a person in which that specific enzyme is deficient or absent. this is done an IV infusion containing the enzyme. Replacing an enzyme in a person in which that specific enzyme is deficient or absent. this is done an IV infusion containing the enzyme. Some enzymes can be replaced by the delivery of a functioning gene Some enzymes can be replaced by the delivery of a functioning gene

9. Retroviruses RNA virus RNA virus Target only actively dividing cells as targets Target only actively dividing cells as targets Higher risk of mutating the genome Higher risk of mutating the genome

10. Adenoviruses Non dividing cells are infected with the virus Non dividing cells are infected with the virus Not as pathogenic as retrovirus Not as pathogenic as retrovirus Used for cystic fibrosis and other lung disorders Used for cystic fibrosis and other lung disorders Small risk of mutation Small risk of mutation

11. Non-Viral Delivery Methods Liposome transfer Liposome transfer Transfer of therapeutic material using phospholipids molecules Microinjection Microinjection DNA is injected into the nucleus of an animal cell
