Rosalind Franklin's x-ray diffraction images of DNA gave James Watson and Francis Crick information about DNA's structure.
Rosalind Franklin utilized a method called X-ray crystallography to determine out the 3D form of molecules and made important contributions in understanding the accurate DNA structure.
James Watson and Francis Crick used Franklin's data in creating a three-dimensional form of DNA.
They proved that DNA is a double helix structure and the two strands of DNA are wind around each other like a twisting ladder.
