That the molecule was a double helix and other steriochemical findings, such as bond length, bond distances and amount of water hydrating the molecule.
Rosalind Franklin
Francis Crick and James Watson used existing data and research, particularly X-ray diffraction images of DNA by Rosalind Franklin, to build models of the DNA molecule. They proposed the double helix structure of DNA in 1953, which revolutionized our understanding of genetics and heredity. Their model explained how genetic information is stored and replicated in living organisms.
Elemental carbon can have two different solid phases with differing spatial (position) ... Crystal structures are determined experimentally by X-Ray Diffraction. So the position of the element is determined experimentally by X-ray diffraction of a crystal of the element.
X-ray diffraction data of DNA revealed its double helical structure, with specific measurements indicating a helical repeat distance of around 3.4 angstroms and a complete turn every 10 base pairs. This data was crucial in understanding the molecular structure of DNA and its role in genetic information storage and replication.
Rosalind Franklin used X-ray diffraction to capture images of DNA that provided crucial evidence of its helical structure. Her famous Photograph 51 revealed the pattern of X-ray diffraction that indicated DNA's spiral shape, which later contributed significantly to the discovery of the DNA double helix by James Watson and Francis Crick.

Double-helix (or spiral staircase). They used x-ray diffraction data from Rosalind Franklin to determine this.

X-ray diffraction
Rosalind Franklin, a biophysicist, used X-ray diffraction to capture images of DNA's structure. These images provided crucial data that helped Watson and Crick in determining the double helix structure of DNA.

DNA images are made using techniques such as gel electrophoresis for separating DNA fragments based on size, and polymerase chain reaction (PCR) for amplifying specific DNA sequences. Fluorescent dyes or radioactive labels can be used to visualize DNA bands on gels, while fluorescence in situ hybridization (FISH) allows for DNA mapping within cells. Advanced imaging techniques like fluorescence microscopy and electron microscopy can provide detailed structural information about DNA.
Atomic number of any element is determined by its X-ray diffraction. Since, X-rays have very high penetrating power, they are used for such purposes. The X-ray diffraction provides idea about the composition of an atom and hence scientists are able to determine the properties of the element.
