James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin

In 1962 James Watson (1928- ), Francis Crick (1916- ), and Maurice Wilkins (1916- ) jointly received the Nobel appraise in medicine or physiology for their determination in 1953 of the twist of deoxyribonucleic social disease (desoxyribonucleic acid). Beca using up the Nobel Prize laughingstock be awarded only if to the living, Wilkinss colleague Rosalind Franklin (1920-1958), who died from cancer at the age of thirty-seven, could not be honored. James Watson and Francis Crick The molecule that is the screwing for genetic endowment, deoxyribonucleic acid, contains the patterns for constructing proteins in the body, including the various enzymes. A new understanding of heredity and hereditary disease was possible once it was determined that DNA consists of two custody twisted around each other, or double helixes, of alternating phosphate and sugar groups and that the two shackles are held together by hydrogen bonds between pairs of pure(a) bases--adenine (A) with thym ine (T) and guanine (G) with cytosine (C). Modern biotechnology in any case has its basis in the structural acquaintance of DNA--in this case the scientists cleverness to modify the DNA of host cells that ordain then mother a desired product, for example, insulin. The background for the lap of the four scientists was organize by several scientific breakthroughs: the relegate made by X-ray crystallographers in studying primitive macromolecules; the growing state supplied by geneticists that it was DNA, not protein, in chromosomes that was prudent for heredity; Erwin Chargaffs data-based finding that there are check numbers of A and T bases and of G and C bases in DNA; and Linus Paulings stripping that the molecules of some proteins have helical shapes--arrived at through the use of atomic models and a keen noesis of the possible impulse of various atoms. Of the four DNA researchers only Rosalind Franklin had university degrees in chemistry. The daughter of a prominent ...
