The role James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin had in finding the structure of DNA

In 1962 James Watson (1928-today), Francis Crick (1916-2004), and Maurice Wilkins (1916-2004) jointly received the Nobel respect in medicine or physiology for their determination in 1953 of the an atomical structure of deoxyribonucleic venereal disease (DNA). Because the Nobel Prize can be awarded sensation to the living, Wilkinss colleague Rosalind Franklin (1920-1958), who died of genus Cancer at the age of 37, could non be honored. The background for the land of the four scientists was formed by several(prenominal) scientific breakthroughs: the increase made by X-ray cryst entirelyographers in studying native macromolecules; the growing evidence supplied by geneticists that it was DNA, not protein, in chromo both(prenominal)s that was prudent for heredity; Erwin Chargaffs experimental finding that at that place are peer numbers of A and T bases and of G and C bases in DNA; and Linus Paulings discovery that the molecules of some proteins have helical shapes--arrived a t through the use of atomic models and a keen fellowship of the possible disposition of variant atoms. Of the four DNA researchers only Rosalind Franklin had any degrees in chemistry. The little girl of a prominent capital of the United Kingdom banking family, where all children--girls and boys--were encouraged to develop their individual aptitudes, she held her under alum and grade degrees from Cambridge University.

During World War II she gave up her research comprehension to contribute to the war effort at the British cleaning lady Utilization Research Association, where she performed fundamental investigations on the properties of coal and graphite. ulterior the war she joine d the Laboratoire Centrale des Services Chim! iques de lEtat in Paris, where she was introduced to the advance of X-ray crystallography and rapidly became a respected authority in this field. In 1951 she returned to England to Kings College, London, where her charge was to upgrade the X-ray crystallographic laboratory at that place for work with DNA. Already at work at Kings...
