Franklinâs images allowed James Watson and Francis Crick to create their famous two-strand, or double-helix, model. At Kingâs College London, Rosalind Franklin obtained images of DNA using X-ray crystallography, an idea first broached by Maurice Wilkins.
Rosalind Franklin in DNA Rosalind Franklin used crystallography to make an x-ray image of the structure of DNA that led to the discovery of the double-helix by Watson and Cric â¦ k.osalind Franklin helped Watson and Crick view DNA by the use of x-rays. Her x-rays helped Watson and Crick build a model of a DNA molecule made out of tin that helped scienti â¦ st better understand the structure of DNA. 6 people found this useful.
