Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling, [2] [3] a postgraduate student working under the supervision of Maurice Wilkins and Rosalind Franklin at King's College London, while working in Sir John Randall's group.
The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. In human DNA, for example, the four bases are present in these percentages: A=30.9% and T=29.4%; G=19.9% and C=19.8%.
The following table is a representative sample of Erwin Chargaff's 1952 data, listing the base composition of DNA from various organisms and support both of Chargaff's rules. [14] An organism such as φX174 with significant variation from A/T and G/C equal to one, is indicative of single stranded DNA.
Earlier this year a picture re-emerged that showed what Jesus might have looked like as a kid. Detectives took the Turin Shroud, believed to show Jesus' image, and created a photo-fit image from ...

Later, Erwin Chargaff(1950) discovered that the makeup of DNA differs from one species to another. These experiments helped pave the way for the discovery of the structure of DNA. In 1953, with the help of Maurice Wilkins and Rosalind Franklin's X-ray crystallography, James Watson and Francis Crick proposed DNA is structured as a double helix. [1]
Such images functioned as powerful relics as well as icons, and their images were naturally seen as especially authoritative as to the true appearance of the subject. Like other icon types believed to be painted from the live subject, such as the Hodegetria (thought to have been painted by Luke the Evangelist), they therefore acted as important references for other images in the tradition.
Many of the AI photos draw in streams of users commenting “Amen” on bizarre Jesus images, praising the impressive work of nonexistent artists or wishing happy birthday to fake children sitting ...
