Hace 15 horas · 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.
Hace 2 días · 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. The breakthrough led to significant advances in scientists’ understanding of DNA replication and ...
1 de jul. de 2024 · The structure of DNA was determined by American geneticist James Watson and British biophysicist Francis Crick in 1953. Watson and Crick based their model largely on the research of British physicists Rosalind Franklin and Maurice Wilkins, who analyzed X-ray diffraction patterns to show that DNA is a double helix.
27 de jun. de 2024 · Learn about Watson and Crick's double-helix DNA structure, composed of two intertwined chains of nucleotides resembling a spiral ladder
Hace 3 días · 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.
Hace 1 día · Late in 1951, Francis Crick started working with James Watson at the Cavendish Laboratory within the University of Cambridge. DNA's role in heredity was confirmed in 1952 when Alfred Hershey and Martha Chase in the Hershey–Chase experiment showed that DNA is the genetic material of the enterobacteria phage T2 .
15 de jun. de 2024 · Sin embargo, una de las fotografías obtenidas por la investigadora llegó a manos de los científicos James Watson (1928) y Francis Crick (1916-2004). Ambos continuaron la investigación y mejoría de los modelos de Franklin y, en 1953, publicaron los estudios y conclusiones, sin dar crédito en ningún momento del trabajo de Rosalind Franklin.
