Há 3 dias · After seeing Franklin's x-ray images of DNA and her report on DNA's symmetry, Watson and Crick built a revised model of DNA's structure: a double helix with sugar-phosphate backbones running in opposite directions.
23 de jun. de 2024 · James Watson - Wikipedia. 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 then began considering the possibility of a two-strand helix with an external sugar-phosphate backbone, and the bases paired like-with-like on the inside of the spiral. Unfortunately, ...
