Photo 51 is an image of the DNA structure that was used to create a DNA template. Rosalind Franklin managed to photograph a DNA molecule.
<h3>Who took the first DNA picture?</h3>
During the four years she spent in France, Rosalind Franklin perfected herself in the use of x-ray crystallography, a technique used to create images of microscopic elements. It was through her that, already at King's College, chemistry managed to photograph a DNA molecule.
With this information, we can conclude that Photo 51 is an image of the DNA structure that was used to create a DNA template. Rosalind Franklin managed to photograph a DNA molecule.
