Study Notes
Structural Model of Deoxyribose Nucleic Acid
- The article was published in Nature on April 25, 1953, Volume 171, page 738
- Authors are James D. Watson and Francis H.C. Crick
- The article outlines a new structural model for deoxyribose nucleic acid (DNA)
- The authors acknowledge the work of Linus Pauling and Robert Corey, who proposed a three-chain helical structure for DNA
- However, the authors suggest a different model, a two-chain helical structure
- This model is based on experimental data from X-ray diffraction patterns of DNA fibers
- Key contributors to this model include:
- M. H. F. Wilkins
- R. Franklin
- E. Chargaff
- G. R. Wyatt
- W. T. Astbury
- The authors received financial support from the National Foundation for Infantile Paralysis
- The work was conducted at the Medical Research Council Unit for the Study of the Molecular Structure of Biological Systems at the Cavendish Laboratory, Cambridge
- The authors cite references to previous work, suggesting that the new model built upon existing research and knowledge.
