Final Thoughts

  • When looking at her contribution to science, and just looking at her life in general, it is easy to see just how resilient Rosalind really was.
  • She battled immense sexism, and defied many odds in her pursuit to research DNA.
  • Some people look at her work as a great contribution to science, and believe that, if she had been alive, she would have received the Noble Prize along side Wilkins, Watson, and Crick.
  • No one will ever know what she could have done if her life hadn't been ended so short, but we do know, that she changed how we look and think about Biology, and for that, we thank her.

After DNA

  • After initial research, she moved to J.D Bernal’s lab at Birckbeck College
  • She continued to researched things like the tobacco mosaic virus, and the polio virus.
  • In 1958, after battling cancer for almost 2 years, she died at the age of 37.
  • In 1962, 4 years after Rosalind’s death, Watson, Crick and Maurice were awarded Nobel Prize in Physiology or Medicine because of their solution to the structure of DNA.
  • Although it was Franklin’s work, she was not recognized in the award.

Debuting

Her DNA

First

Published Work

  • When preparing to debut her findings, Crick and Watson published their research in a similar style.
  • It is thought that her colleague Wilkins actually showed Crick a copy of her X-rays and studies, without Rosalind’s permission.
  • This new information is thought to have to lead Crick and Watson's understanding of DNA structure replication
  • The two men published their advancements in an article in “Nature”.
  • Rosalind was not credited for any of her research in this article.

  • Between the years 1951 and 1953, she discovered many new and interesting things about DNA’s structure
  • She actually produced X-Ray photographs of DNA.
  • J.D Bernal, a very controversial scientist of the 20th century, commented on her x-ray, calling it, “the most beautiful X-Ray photographs of any substance ever taken.”

Continued Research on DNA

  • She was the first to discover the double helix shape.
  • First thought she was seeing a triple helix, but then concluded there were only 2 strands.
  • Franklin initially thought that the bases of a DNA structure were on the outside with the phosphate was on the inside.
  • Her experiment also revealed that the opposite was true. The phosphate attaches to the pentose sugar, with a hydrogen bond attaching the bases.

Early Life and Research

Who is Ros?

  • After earning a PhD in physical chemistry at Newnham College, she studied in Paris and learned all about X-ray crystallography.
  • With new knowledge, she returned to England and found an interest in the structure and research of DNA.
  • Met Maurice Wilkins, and faced extreme sexism at Kings College in London.

  • Born and raised in London, England
  • She became interested in the sciences at the age of 15
  • Attended Newnham College, Cambridge and Laboratoir Central des Services Chimiques de L'Etat in Paris
