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

DNA: Definition, Structure & Discovery DNA was first observed by a German biochemist named Frederich Miescher in 1869. But for many years, researchers did not realize the importance of this molecule. It was not until 1953 that James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin figured out the structure of DNA — a double helix — which they realized could carry biological information.

Discovery of DNA Structure and Function: Watson and Crick Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.hargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.

Francis Crick: DNA Discoveries, Overview Also in 1953, Crick and an American scientist named James Watson made what was probably the biggest discovery of their careers, which was the structure of the DNA molecule. This effort led both men (along with Maurice Wilkins and Rosalind Franklin) to the Nobel Prize in Physiology or Medicine in 1962.

Structure Discovery Frederick Miescher - is the man who discovered DNA. The Swiss physician isolated a high phosphorous-containing substance from white blood cell nuclei in 1869. It was DNA, which he called 'nuclein' because it had come from the nucleus. He did not know its true nature.

Concept 19 The DNA molecule is shaped like a twisted ladder. Watson and Crick were at the Cavendish Laboratory and had been working on solving the DNA structure. Franklin did not know Watson and Crick as well as Wilkins did and never truly collaborated with them. It was Wilkins who showed Watson and Crick the X-ray data Franklin obtained.The data confirmed the 3-D structure that Watson and Crick had theorized for DNA. In 1953, both Wilkins and Franklin published papers on their X-ray data in the same Nature issue with Watson and Crick's paper on the structure of DNA.atson and Crick were at the Cavendish Laboratory and had been working on solving the DNA structure.

The First Discovery of DNA Ralf Dahm. Most everybody knows that DNA contains the blueprint for life. The names of Watson and Crick, the first scientists to figure out the structure of DNA in the 1950s, are also widely recognized. But left obscure in history is the name of the chemist who first isolated the DNA molecule itself.

Home / Learn / Historical Biographies 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.

Rosalind Franklin and the DNA Scavenger Hunt In 1962, James Watson, Francis Crick and Maurice Wilkins got the Nobel Prize for the discovery of the shape of DNA. Photo 51 was an X-ray diffraction image that gave them some crucial pieces of information. It was only after seeing this photo that Watson and Crick realized that DNA must have a double helical structure. The problem was that Photo 51 was actually made by Rosalind Franklin.
