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.
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.
Jun 20, 2002 · The American biochemist Erwin Chargaff (born 1905) discovered that DNA is the primary constituent of the gene, thereby helping to create a new approach to the study of the biology of heredity. Erwin Chargaff was born in Austria on August 11, 1905.
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.
His two main discoveries, (i) that in any double-stranded DNA the number of guanine units equals thenumber of cytosine units and the number of adenine units equals the number ofthymine units and (ii) that the composition of DNA varies from one species toanother, are now known as Chargaff's Rules.
Jun 18, 2024 · Ukrainian-born US biochemist who became professor of biochemistry at Columbia University (1952–74). Stimulated by Oswald Avery's identification of DNA as the basis of heredity in pneumococcus bacteria, he discovered that the constitution of DNA is consistent within a species but that there are as many types of DNA as there are species.
