Traveller's Gift Presentation
Transcript: Thank You ! In the base composition of DNA, the quantity of adenine equales the quantity of thymine; the quantity of guanine equales the quantity of cytosine Erwin Chargaff Most Known: Occupation: Birthday: On Traveller's Gift 11 August 1905 His Researches Includes... Bio Blue The basic rules of DNA DNA’s base composition the ratio of purines to pyrimidines DNA function and structure Chargaff's Rules Chargaff's findings, along with those of Rosalind Franklin's X-ray diffraction studies of DNA, strongly suggested that base-pairing existed within DNA between A and T, and between G and C. Two years later, he explained these findings to James Watson and Francis Crick, who were then able quickly to elucidate the double-helix structure of DNA. Not much luck... 1905-2002 Chernivtsi- Turning Point in His Life A city in Austria-Hungary In my opinion, the eighth decision would be: Travel ten thousand miles. It means you should travel and see things throughout the world. In this way, you can have more experience, and you can stay calm in all situations. Also, you can get in touch with more people, which helps you consummate your ideas. Erwin Chargaff The Eighth Decision: After being in Paris for a little while, Chargaff found a research position at Columbia University’s Department of Medicine He remained there for the rest of his career 1940: He became a U.S. citizen Austrian-American Nationality: 1933: He was about to receive Habilitationschrift, a formal condition for becoming a university professor; Due to the rise of Nazi's power, he was considered from a a family of Austrian Empire Jews He left Berlin Chargaff's Rule (By 1950) Chargaff's Rules About Erwin Chargaff 1928: received a doctorate-- Vienna University of Technology (analytical chemistry) 1928~1930: postdoctoral research--Yale University (bacterial chemistry) 1930~1933: a privatdozent, or occupant of the first ladder in a professorial career--University of Berlin’s Department of Public Health Chargaff was invited to work at the Pasteur Institute in Paris Albert Calmette used Chargaff to help himself out of the responsibility of contaminating the Bacille Calmette-Guerin vaccines (Calmette was the inventor of the vaccine) After 2 years, he left again with the flow of the refugees from the Germans Settling in America Birth Place: Biochemist Education Background Time period: Casie Jin 19 April 2012
