WebPauling came up with the solution by starting with X-ray diffraction data, then using ball-and-stick model-building as a shortcut. This approach had allowed him to find the solution much more quickly than he could have by using X-ray data alone. The success of his approach inspired Watson and Crick to try the same thing. Previous WebThe scientist Linus Pauling was eager to solve the mystery of the shape of DNA. In 1954 he became a Nobel Laureate in Chemistry for his ground-breaking work on chemical bonds and the structure of molecules and crystals. In early 1953 he had published a paper where he proposed a triple-helical structure for DNA. WebA bioinformatic analysis of the S. cerevisiae genome observed the occurrence of H-DNA and other triplate DNA motifs in four organizational regions: introns, exons, promoter regions and miscellaneous regions.
