Study Notes
Scientists and their Discoveries
- Rosalind Franklin was a British chemist whose work on the structure of DNA was vital to the discovery.
- Franklin's work, though overlooked during her lifetime, was essential to understanding DNA structure.
- Franklin studied X-ray crystallography to examine the molecular structure of DNA.
- In 1951, Franklin began photographing DNA strands at King's College, London.
- A team of scientists (including Watson and Crick) used X-ray crystallography to interpret the structure of DNA.
- Maurice Wilkins shared Nobel Prize in Physiology or Medicine in 1962 with Watson and Crick.
- Francis Crick and James Watson were part of a team developing the structure of DNA.
- Francis Crick and his research partner, who worked on and solved the structure of DNA, published "the secret of life".
- Their work on DNA was significant in the 20th Century.
Dynamic Duo
- Crick and Watson applied themselves to the investigation with single-minded focus.
- They pooled their evidence from other scientists and combined their knowledge of disciplines (viral genetics, physics, and X-ray crystallography).
- They built 3D models of DNA according to its known chemical properties.
- After two failed attempts, their success was made possible by Rosalind Franklin's data.
- Watson and Crick's work was published in a single-page paper (Nature, 1953).
Sydney Brenner
- South African biologist Sydney Brenner was one of the first to see the Watson and Crick DNA model.
- Brenner completed a PhD at Oxford University and conducted research into developmental genetics.
- Brenner discovered the encoding process for amino acids.
- Brenner's work was on developmental genetics (organ development and cell death).
- He was jointly awarded the Nobel Prize in 2002 for his work on organ development and cell death.
Other accomplishments
- Francis Crack was awarded a Nobel Prize in 1962.
- Maurice Wilkins received a Nobel Prize.
- Other scientists made other significant scientific discoveries related to DNA including its structure and functioning.
