Photograph 51
Photograph 51 was an x-ray diffraction image of the DNA molecule taken, by Rosalind Franklin and Raymond Gosling on May,1952 in Kings College, London. This x-ray provided information that was crucial in identifying the structure of DNA.
Franklin's deep exploration in the structure of DNA also led to the basis for the genetic code, which then led on to the Cracking of the Human Genome, while also encountering some obstacles such as sexism by the men in her field she jumped over them and came out victorious From that photo scientists were able to determine the diameter of a DNA molecule, the distances between the nitrogenous bases, the number of nitrogenous bases in each turn of the DNA molecule. With the photo the exact configuration of the nitrogenous based had not yet been determined. |

She was never given any credit or recognition by Watson and Crick. However in a 1990 interview Watson mention the Dr. Franklin had provide some information that was useful.

The Double Helix
The Double Helix was a model of the structure of DNA. The Double Helix model , created by James Watson and Francis Crick, went on to win a Nobel prize not long after Franklin had died of Ovarian Cancer, yet Rosalind's contribution to this model did not go unnoticed, because of the controversy that soon arrived about the misuse of sources that blamed Watson, and Crick.

Watson and Crick along with Wilkins were all awarded the Noble Prize in 1962. The material and articles they published could not have been accomplished without Dr. Franklin famous Photo 51. |
