interview, or work through an experiment to resolve the clue.
Scientists to find:
James Watson
Francis Crick
Craig Venter
Gregor Mendel
Frederick Meischer
Frederick Griffith
Rosalind Franklin
Sydney Brenner
Erwin Chargaff
Fredrick Sanger
Clues
1. It took him eight years and more than 10,000 pea plants to discover the laws of inheritance.
________________________________________
2. He determined base pairing rules. A-T and G-C
_______________________________________
3. When did Drs. Watson and Crick and Wilkins receive the Nobel Prize in Physiolgoy or Medicine for solving the structure of
DNA?
_______________________________________
4. J. Craig Venter’s Company, Celera Genomics, worked on this very important project.
________________________________________
5. I first isolated DNA using pus collected from bandages at a local hospital. Since white blood cells are a major component of
pus, they were my source of DNA. YUCK!
_________________________________________
6. Determined that mRNA carries the code from the DNA to ribosomes for protein production.
________________________________________
7. By using X-Ray diffraction I was able to determine the twisting nature of a DNA molecule. My worked helped Watson and
Crick solve the puzzle.
________________________________________
8. Determined amino acid sequences in certain protein, like insulin. Won a 2 Nobel Prizes for his work.
_________________________________________
9. Determined that a factor in heat killed, disease causing bacteria can “transform” harmless bacteria into ones that cause
disease.
