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.
Erwin Chargaff was awarded the National Medal of Science for fundamental chemical and biological studies establishing the basis for modern concepts of the mechanisms of protein synthesis and the genetic role of nucleic acids.
Jun 30, 2002 · Erwin Chargaff, whose research into the chemical composition of DNA helped lay the groundwork for James Watson and Francis Crick's discovery of its double-helix structure -- the pivotal...
