  1. Erwin Chargaff (11 August 1905 – 20 June 2002) was an Austro-Hungarian-born American biochemist, writer, Bucovinian Jew who emigrated to the United States during the Nazi era, and professor of biochemistry at Columbia University medical school. [1]

  2. One other key piece of information related to the structure of DNA came from Austrian biochemist Erwin Chargaff. Chargaff analyzed the DNA of different species, determining its composition of A, T, C, and G bases. He made several key observations: A, T, C, and G were not found in equal quantities (as some models at the time would have predicted)

  3. Erwin Chargaff Lived 1905 – 2002. Erwin Chargaff’s research paved the way for the discoveries of DNA’s structure and its method of replication. His observation that DNA varies from species to species made it highly credible that DNA was genetic material.

  4. Erwin Chargaff was one of those men, making two discoveries that led James Watson and Francis Crick to the double helix structure of DNA. At first, Chargaff noticed that DNA – whether taken from a plant or animal – contained equal amounts of adenine and thymine and equal amounts of cytosine and guanine.

  5. Erwin Chargaff (1905-2002) was born in Czernowitz, which at that time was aprovincial capital of the Austrian monarchy. He graduated from high school atthe Maximilian Gymnasium in Vienna and went to the University of Vienna in1923. “I was eighteen and the world was before me,” notedChargaff.

  6. Dec 30, 2021 · Erwin Chargaff was an Austrian-Hungarian biochemist born in Czernowitz, Austria who developed the Chargaff Rules. These rules helped to determine and established the pattern of nitrogenous base...

  7. The biochemist Erwin Chargaff had found that while the amount of DNA and of its four types of bases--the purine bases adenine (A) and guanine (G), and the pyrimidine bases cytosine (C) and thymine (T)--varied widely from species to species, A and T always appeared in ratios of one-to-one, as did G and C. Maurice Wilkins and Rosalind Franklin had …
