Full name is Rosalind Elsie Franklin was a physicist - chemistry and British scientists. The study on the structure of DNA by refraction of rays, x-ray (AD 1920-1958), "Roslyn" has studied DNA from the refraction of x-ray radiation that has a spiral shape or a spiral pattern. (helical) by a group of phosphate in a catch together outside of this spiral, "Roslyn" worked with Maurice Wilkins began to have important information about the structure of DNA from doing. trial The X-ray technique World graphene crystal (x - rays crystallography), they calculated from X-rays and found that the DNA will handle more than one call. And a repetitive structure may also be formed to catch more than one as well.
