History of DNA
Texte du Storyboard
- In the early 1950s, Watson and Crick were two of several scientists trying to figure out the structure of DNA
- Oh fine, you can be my lab partner! I'll just do all the work and hopefully beat Pauling.
- Oh it seems like everyone has a lab partner except you and I, Crick.
- Hmm, that's not a terrible idea actually..
- Since nothing's working, why don't we try my idea, analyzing the ideas of other scientists and seeing what we come up with?
- Franklin was an expert in X-ray crystallography.
- Photograph 51
- Oh my! Franklin's X-ray diffraction image of DNA is so clear!
- It all makes sense now, the X-shaped diffraction pattern means DNA has a three-dimensional double helix.
- The Nobel Prize in Medicine was presented to Watson, Crick, and Wilkins in 1962. Unfortunately, Franklin had already died by that time, and Nobel prizes are not given out posthumously.
- Nobel Prize
- Watson and Crick's discovery of the double helix, the twisted-ladder structure of DNA, in 1953 was a historical moment in science, paving the way for contemporary molecular biology.
- 30 years later
- You weren't such a bad lab partner after all.
- We made history!
