question 92

Multiple Choice

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.
