How does x-ray crystallography provide details about molecular structure?

a. Only DNA molecules scatter x-rays; therefore, this helped to prove that DNA was the genetic material in cells.
b. X-rays are reflected by some atoms and absorbed by others; thereby giving clues to molecule structure.
c. X-rays are scattered by atoms in a specific pattern, from which molecular size, shape, and spacing of repeating
elements can be calculated.
d. This technique captures photographs of magnified molecules.
e. X-rays can be used to isolate DNA molecules from living organisms.
