Discovery of the Structure of DNA Essay -- History Historical Science

Discovery of the Structure of DNAOn the last day of February in 1953, according to James Watson, Francis Crick announced to the patrons of the Eagle gin mill in Cambridge, We have discovered the secret of life (Watson 115, 1980). As Brian Hayes, the reservoir of The Invention of the Genetic Code states, If life ever had a secret, the dual helix of DNA was surely it (1). However, it was not the work of these two work force alone that led to the discovery of the power the lies within the double helix, entirely rather the work of many scientists that was c arfully picked apart and pieced together by the two who received the most fame for the work. Scientists knowledge of DNA was reported as early as 1868, when the Swiss physician Fritz Miescher discovered its presence in the nuclei of cells (Frank-Kamenetskii 10, 1997). Until the study of the anatomical structure of DNA led to the discovery of its function, proteins were primarily thinking to be the carriers of genetic material. Although the chemical composition of DNA was Francis Crick cognize and understood, scientists were unable to make conclusions about its function (Patterson 17, 1999). In 1958, Crick presented his scientific paper, On Protein Synthesis at the Society for Experimental Biology. Within his textbook he states, It is an essential feature of my argument that in biology proteins are uniquely important . . . their nearest rivals are the nucleic acids. Watson said to me, a some years ago, The most signifi beart thing about nucleic acids is that we dont know what they do. By contrast, the most significant thing about proteins is that they can do almost anything (Carlson 236, 1989). Watsons statement led the pair to moreover investigate the mystery of life by delving through ot... ...801.html, 25 butt 2001- James Watson.
