The pioneering reasearch that revealed the general structure of DNA was performed by Francis Crick, James Dewey Watson, and Maurice Wilkins. Wilkins obtained an x-ray diffraction picture of the DNA molecule in 1951. Using this picture, Crick and Watson were able to construct a model of the DNA molecule that was complete in 1953. For their work, these scientists recived the 1962 Nobel Prize in physiology or medicine. Arthur Kornberg synthesized DNA from "off-the-shelf" substances, for which he was awarded with Severo Ochoa the 1959 Nobel Prize in physiology or medicine. The DNA thatr he synthesized, although structurally similar to natural DNA, was not biologically active. In 1967, however, Kornberg and a team of researchers at Stanford University succeeded in producing biologically active DNA from relatively simple chemicals.
