- The Discovery of DNA's Structure
- Rosalind Franklin
- Maurice Wilkins
- Francis Crick
- James Watson
- Look what I just discovered! I managed to generate the first image of the structure of DNA!
- Please dont share my findings to anyone yet, I still have some research to conduct.
- Alright I promise I will keep this information a secret
- This is a massive breakthrough in the field of genetics! Lets share this great news!
- King's college LondonMay 1952
- I was told to keep this a secret, but she wont find out.
- This is a photo we named "Exposure 51" which shows the structure of the DNA, although we are unsure how DNA store genertic information
- We utilized X-ray crystallography, which allows us to shoot X-rays at the molecule's component parts, which then bounce off create a shadow of the structure of DNA.
- This is amazing. How did you manage to produce this photo?
- King's college London Janurary 1953
- That image is fascinating, we need to reproduce that image in order to further our understanding of genetics. I have access to similar X-rays at the cavendish laboratory, so I will provide images to you to study.
- Once I receive the photos I will begin my experiements and create models of possible DNA structures.
- King's college London Janurary 1953
- Let's announce our discovery on the upcoming issue of "Nature"
- Essentially I looked that the images produced by the image produced from an X-ray being shot onto the DNA. I then identified the defraction pattern of the segemented "X" shape. This pattern was very similar that of a spring's refraction pattern, so with a bit more persistence I was able to identify the structure of the DNA.
- How were you able to figure out the structure of DNA?
- Hey Franklin I had had a series of breakthroughs! I have identified that DNA is made out of 2 chains of nucleotides; which form a double-helix.
- King's college London April 1953
- 1962,Nobel Prize in Physiology or Medicine
- The End
- I would like to present the 1962 Nobel Prize in Physiology or medicine to James Watson, and Francis Crick on their discovery of the structure of DNA
- 9 Years later
