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.

Question

Quizplus · Accepted Answer

X-ray crystallography works by directing X-rays at a crystal structure. The atoms within the crystal scatter the X-ray beams in a way that forms a diffraction pattern. By analyzing these patterns, scientists can deduce the arrangement of atoms within the crystal and thus determine the molecular structure, including the size, shape, and spacing of its components.
