Learn about the life and achievements of Erwin Chargaff, a pioneer of DNA research who discovered its base ratios and structure. Explore his early years in Austria, his travels in Europe and America, and his contributions to science and culture.
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.
