Study Notes
Rosalind Franklin's Life and Work
- Born in 1920, a British chemist
- Graduated from Cambridge University in 1941 with a degree in physical chemistry
- Worked on the chemical structure of coal and graphite
- Earned her doctorate from Cambridge in 1945
- Studied X-ray crystallography in Paris (1947)
- Used X-rays to study crystalline structures and molecular structures
- Made crucial contributions to understanding the structure of DNA (deoxyribonucleic acid) in the 20th century
The Race to Decipher DNA
- In the 1950s, scientists globally sought to understand DNA structure
- DNA encodes genetic information essential to all living things
- James Watson and Francis Crick worked in Cambridge, attempting to model the DNA structure
- In 1951, Rosalind Franklin started photographing DNA strands at King's College, London
- A group of physicists, biologists, and biochemists helped in pioneer biophysics at King's College
- Her X-ray diffraction images revealed the double helix structure of DNA in 1952 (important finding)
Franklin's Contribution and Recognition
- Her critical contribution to the understanding of the DNA molecule was key to defining its structure
- Her work was vital to the discovery of DNA structure; yet, it was largely overlooked during her lifetime
- Her work later became essential to James Watson and Francis Crick's 1953 modelling of DNA structure
- Her work at King's College London was undertaken inadvertently without the knowledge of another researcher (Maurice Wilkins) in 1951
