3. 3 The Human Genome Project An international effort to decipher the DNA blueprint of a human being

5. 5 Human Genome Project Goals: To sequence & determine the exact order of the nucleotides (A,C,T,G) for ALL of the DNA in a human cell To determine which sections of DNA represent the individual genes To store this information in databases for analysis

9. 9 How genes influence an individual’s response to drugs

10. 10 Gene Therapy 1.Isolate the normal sequence for a gene and package it into a virus (vector). 2.Infect a target cell, usually the one with the illness, such as a liver or lung cell. 3.The cell uses the normal sequence to produce the missing protein and is thus repaired. Replacement of an abnormal protein with a normal one

11. 11 Problems with Gene Therapy Short lived, so patients have to go through multiple rounds Immune response to foreign invaders Problems with the viruses Very expensive Multigene disorders: disorders like heart disease, high blood pressure, Alzheimer’s disease, diabetes are caused by the combined effects of variations in many diseases.

12. 12 What is Cloning? Cloning is the creation of an organism that is the EXACT genetic copy of the mother Identical twins are natural clones, they share 100% of their DNA

13. 13 How do you clone an organism? 1.Remove the nucleus from an egg cell and a regular cell from a donor. 2.Fuse the enucleated cell with a regular cell (that still has its nucleus) by electric shock 3.The new fused cell begins dividing, just as a fertilized egg would. 4.The embryo is placed in the uterus of a surrogate mother and allowed to develop normally. 5.The surrogate mother gives birth to a genetic clone of the original egg cell donor donor!
