Multiple Choice

Protein crystals are used in x-ray diffraction studies because

A) the molecules of proteins in a powder or solution are too loose.
B) the diffraction power of a single protein molecule is too low.
C) several molecules of proteins are in a crystal leading to strong diffraction patterns.
D) the molecules of proteins in a powder or solution are too loose and the diffraction power of a single protein molecule is too low only.
E) the molecules of proteins in a powder or solution are too loose,the diffraction power of a single protein molecule is too low,and several molecules of proteins are in a crystal leading to strong diffraction patterns.
