  2. 2. DNA Discovery WALT: Explain the roles of particular scientists in relation to the discovery of DNA. WILF: ~ State what the Human Genome Project is. (D) ~ List some advantages and disadvantages of the human genome project. (C) ~ Describe how DNA was discovered with reference to Crick, Watson, Franklin and Wilkins. (B) ~ Evaluate the impact of the Human Genome Project. (A/A*)
  3. 3. DNA discovery James Watson and Francis Crick Rosalind Franklin and Maurice Wilkins
  4. 4. Describe the roles played by different scientists in the discovery of DNA. ~ Maurice Wilkins and Rosalind Franklin (London) ~ James Watson and Francis Crick (Cambridge)
  5. 5. The Human Genome Project Genome: All the genetic information (DNA) of an organism, as a list in order of every base. 99.9% DNA in common • Scientists in 18 countries. • Started in 1990 and was completed in 2003 the HGP was complete. • Scientists had worked the sequence of over 3 million base pairs that make up the human genome.
  6. 6. The Human Genome Project Summarise what the HGP was. The Human Genome Project (HGP) was… It was completed in… Scientists had found.. Use the information on page 37 to describe ways in which HGP has been used to develop our knowledge in science and medicine.
  7. 7. What would you like to use information from the HGP for?
