To the untrained eye, Photo 51 was simply a grainy black and white image of dark marks scattered in a rough cross shape. But to the eye of a trained scientist, it was a clear portrait of a DNA fiber taken with X-rays. And to young scientists James Watson and Francis Crick, it confirmed their guess of deoxyribonucleic acid's structure. In 1953 the pair was racing toward solving the mystery of DNA's structure before other scientists could beat them to it. They and others believed that finding the simple structure of the DNA molecule would answer a great mystery, how do organisms live, grow, develop, and survive, generation after generation? Photo 51 and subsequent models based on the photo would prove to be the key to unlocking the secret of life.

This book features the character James D Watson.

Francis Crick
Francis Crick was a scientist who worked with James Watson. The two used x ray diffraction to study DNA. In April 1953, they published a paper of their discovery - a molecular structure of DNA based on all its known features - the double helix. Their model served to explain how DNA replicates and how hereditary information is coded on it. This set the stage for the rapid advances in molecular biology that continue to this day. The two scientists - with Maurice Wilkins - won the 1962 Nobel Prize in Medicine for their discovery of the structure of DNA.
