   Jan 5, 2010 · Watson and Crick were two scientists who worked together to confirm the double-helix structure of DNA in 1953. Watson and Crick also came up with a model by which DNA might be replicated: This theory was called semi-conservative DNA replication. The theory is based upon the specific hydrogen bonding between pairs of nitrogenous bases (A+T and C ...

   Scientists collected evidence and shared findings to develop a model to describe the structure of DNA. Rosalind Franklin’s team in London used X-rays to produce an image of a DNA molecule in1952. Maurice Wilkins from Franklin’s group showed the picture to James Watson from Cambridge.

   1. William Astbury. (1898-1961) Astbury was a British molecular biologist and physicist who spent much of his working life in Leeds. His work focused originally on the structure of proteins in textiles but, along with his PhD student Florence Bell, he took the first X-ray photographs of DNA in 1937.

   Did Watson and Crick discover DNA?

   • Watson and Crick were not the discoverers of DNA, but rather the first scientists to formulate an accurate description of this molecule's complex, double-helical structure. Moreover, Watson and Crick's work was directly dependent on the research of numerous scientists before them, including Friedrich Miescher, Phoebus Levene, and Erwin Chargaff.

   What is Watson and Crick's model?

   • One of the ways that scientists have elaborated on Watson and Crick's model is through the identification of three different conformations of the DNA double helix. In other words, the precise geometries and dimensions of the double helix can vary.

   How did Rosalind Franklin discover DNA?

   • At King’s College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins. Franklin’s images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model.

   Sep 18, 2017 · For Crick, four kinds of information transfer clearly existed: DNA → DNA (DNA replication), DNA → RNA (the first step of protein synthesis), RNA → protein (the second step of protein synthesis) and RNA → RNA (RNA viruses copying themselves).
