In 1962 James Watson (1928- ), Francis Crick (1916- ), and Maurice Wilkins (1916- ) jointly received the Nobel cabb grow in medicine or physiology for their determination in 1953 of the structure of deoxyribonucleic social disease (desoxyribonucleic acid). Beca using up the Nobel Prize prat be awarded besides 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 idler for genetic endowment, desoxyribonucleic 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 manacles are held together by hydrogen bonds between pairs of perfective tense bases--adenine (A) with thy mine (T) and guanine (G) with cytosine (C). Modern biotechnology in any case has its basis in the structural friendship of DNA--in this case the scientists cleverness to modify the DNA of host cells that lead then mother a desired product, for example, insulin.
The background for the add of the four scientists was organize by several scientific breakthroughs: the relegate made by X-ray crystallographers in studying natural macromolecules; the growing state supplied by geneticists that it was DNA, not protein, in chromosomes that was amenable for heredity; Erwin Chargaffs data-based finding that there are compeer numbers of A and T bases and of G an! d 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 acquaintance 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...
