Erwin Chargaff was one of the more interesting and colourful figures of the historic decade that heralded the proposal of the double helical structure of DNA by Watson and Crick in 1953. In describing Chargaff's important contribution to the study of DNA, particularly its base composition, this article seeks to suggest why, despite his ...

Jun 27, 2018 · Chargaff's most important contribution to biochemistry was his work with deoxyribonucleic acid, more commonly known as DNA. At the time he was working it was not known that genes were composed of DNA.

In 1944, Chargaff read Oswald Avery’s report that the hereditary units, the genes, were composed of DNA (2). This had a profound impact on Chargaff, as he recollected, “Avery gave us the first text of a new language, or rather he showed us where to look for it. I resolved to search for this text.
Erwin Chargaff. Heraclitean Fire. 1978. "This observation of complementarity, later called Chargaff's ratios, was essential to the solution of DNA's structure. In hindsight, the complementary pairing of the nucleotides powerfully suggested that a DNA molecule could break into two parts.
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure. ID: 15495. Source: DNALC.DNAi.
