  1. Rosalind Franklin

    By Dylan Brown, Alexis Martin, Nick Kennis, and Nichole Heitzenrater
  2. Information on Franklin She was born on July 25, 1920 in London, England. She was offered a 3- year research scholarship at King’s College in London in 1951. Franklin arrived while Wilkins was away, and Wilkins assumed that she was hired to be the assistant. Watson and Crick published papers in the same issue as Franklin in Nature. Watson, Crick, and Wilkins won the Nobel Prize for solving DNA structure in 1962, after her death.
  3. Franklin’s Contributions She was the first to use an x-ray on DNA, which led to the discovery of the DNA double helix. The x-shaped pattern showed that the DNA is twisted around each other. The angle of it suggests that there are two strands in the structure. They also suggest that the nitrogen base is near the center of the DNA molecule.

  5. Franklin’s Experiment Franklin had discovered that DNA could crystallize into 2 different forms. Franklin and Wilkins worked on this project. They used x-ray crystallography to do this experiment, and they concluded that, if the pattern is clear enough, one can see the arrangement of the atoms in a molecule. Franklin also discovered that DNA had an A and B form. After 100 hours of x-rays, she discovered the essential structure of DNA. This included the strands of DNA and the number. She was unable to explain the bases, and that was explained by Watson and Crick.
  6. Franklin’s Connections At a lecture at King’s College neither of them knew what the lecture really meant until Wilkins showed Watson and crick the X-Ray data when they were studying the DNA structure that confirmed their data, they both ten published papers on the subject.
