Verified step by step guidance1
Understand that X-ray diffraction is a technique used to study the three-dimensional structure of molecules by observing the pattern of X-rays scattered by the electrons in the molecule.
Recognize that Rosalind Franklin's X-ray diffraction image, known as Photo 51, provided critical insights into the structure of DNA.
Note that the diffraction pattern indicated a helical structure, as evidenced by the X-shaped pattern observed in the image.
Identify that the specific dimensions and angles in the diffraction pattern suggested a double helix structure, with two strands winding around each other.
Acknowledge that this discovery was pivotal in understanding the molecular structure of DNA, leading to the realization that DNA is a double helix, which was later modeled by Watson and Crick.
