In 1948, Linus Pauling discovered that many proteins take the shape of a helix. At Cambridge University, James Watson and his research partner Francis Crick had become interested in Linus Paling’s work. Their approach was to try to make a physical model of what DNA looks like to narrow down the possibilities and eventually create an accurate model of the molecule. In 1951, Watson attended Rosalind Franklin’s lecture on the current work that she had done. Rosalind discovered that DNA could exist in two forms and also discovered that within her x-Ray of DNA, the wet form of DNA had all the characteristics of a helix. Watson and Crick, after later looking at Franklin’s results, suggested that the molecules of DNA were made of two
