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 cherish in medicine or physiology for their determination in 1953 of the grammatical construction of deoxyribonucleic venereal disease (DNA). Because the Nobel Prize can be awarded mavin 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 close to(prenominal) scientific breakthroughs: the increase made by X-ray cryst wholeographers in studying native macromolecules; the growing evidence supplied by geneticists that it was DNA, not protein, in chromosomes 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 at through the use of nuclear models and a keen fellowship of the possible disposition of unhomogeneous atoms. Of the four DNA researchers only Rosalind Franklin had any degrees in chemistry. The young woman 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 ammonia alum degrees from Cambridge University.

During World War II she gave up her research encyclopaedism to contribute to the war effort at the British blacken Utilization Research Association, where she performed fundamental investigations on the properties of coal and graphite. subsequently the war she joined the Laboratoire Centrale des Services Chimi! ques de lEtat in Paris, where she was introduced to the increase 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 thither for work with DNA. Already at work at Kings...
