Biophysicist and X-ray crystallographer made breakthroughs in the field of DNA structure

Today would be the renowned British biophysicist Rosalind Franklin's 93rd birthday and Google are marking it with a personalised Doodle.

Franklin, who was born on 25 July 1920, made critical contributions in the field of genetics, and in particular made breakthroughs in the understanding of the fine molecular structure of DNA. Her discovery of the structure of DNA - or deoxyribonucleic acid - helped her colleagues understand how genetic information is passed from parents to children.

The Doodle on Google's home page shows a cartoon illustration of Franklin looking at the DNA double helix - eluding to her work on the X-ray diffraction images of DNA, which in turn led to the discovery of its distinctive structure.

Franklin studied for her first degree and PhD at the University of Cambridge, before traveling to work in France and returning to be a research associate at King's College London, where she worked on the X-ray diffraction analysis.

She died on 16 April, 1958, in Chelsea, after a two-year battle with cancer.
