Final answer:
X-ray diffraction can be used in X-ray crystallography to determine the structure of crystals, including the A and B forms of DNA. This technique was employed by Rosalind Franklin, James Watson, and Francis Crick to reveal the helical nature of DNA.
Step-by-step explanation:
X-ray crystallography is a process that can yield information about the structure of crystal materials. X-ray diffraction can be used in X-ray crystallography to determine the structure of crystals, including the A and B forms of DNA. This technique was employed by Rosalind Franklin, James Watson, and Francis Crick to reveal the helical nature of DNA.
By scattering X-rays from a crystal, a diffraction pattern is produced, which can provide details about the atomic arrangements within the crystal. This technique was used by Rosalind Franklin, along with James Watson and Francis Crick, to determine the shape and structure of DNA.
In the case of DNA, the A and B forms can be visualized through X-ray diffraction, revealing the helical nature of DNA and providing valuable insights into its structure.
