Answer:
X-ray beam was targeted at a crystallized DNA molecule Beam was diffracted = scattering pattern recorded on film pattern shows structural features of DNA molecule Composition: double stranded, tightly packed, regular Orientation: Sugar-phosphate backbone, bases inside Shape: double helix Data shared by Wilkins to Watson and Crick without her permission to create a DNA model
