Há 2 dias · Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College London, particularly Photo 51, taken by her student Raymond Gosling, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962.
Há 1 dia · In 1953 James Watson and Francis Crick, aided by the work of biophysicists Rosalind Franklin and Maurice Wilkins, determined that the structure of DNA is a double-helix polymer, a spiral consisting of two DNA strands wound around each other.

11 de jun. de 2024 · A célula monoclínica era um deles, o que fortalecia a interpretação de Rosalind Franklin. A partir daí, Watson e Crick formularam hipóteses, fizeram cálculos e construíram modelos físicos com peças de cartolina recortadas, arames e latas. Trabalharam em aproximações sucessivas. Eis o relato de Crick:
Há 3 dias · James Watson. James Dewey Watson (born April 6, 1928) is an American molecular biologist, geneticist, and zoologist. In 1953, he co-authored with Francis Crick the academic paper proposing the double helix structure of the DNA molecule. Watson, Crick and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine "for their ...
22 de jun. de 2024 · This photograph and her precise measurements of the DNA helix’s dimensions were crucial in guiding James Watson and Francis Crick toward their model of the double helix structure of DNA.
26 de jun. de 2024 · In their 1953 paper in the British journal Nature, James D. Watson and Francis H. C. Crick, who first constructed a model of the DNA molecule, barely mentioned Dr. Franklin and gave her none of the credit for their conceptual breakthrough.
1 de jul. de 2024 · The duo, 25-year-old American bacteriologist and birdwatcher James Watson and Francis Crick, a 37-year-old British physicist, announced that they had unravelled the double helix structure of deoxyribonucleic acid, DNA, saying: “We have discovered the secret of life!”.
