Question

Quizplus · Accepted Answer

The reflection positions and intensities on the photographic plate of an X-ray crystallography experiment are related to the electron densities of proteins. X-rays interact with the electron cloud surrounding the atoms in the protein, causing them to scatter in a pattern that can be analyzed and used to determine the structure of the protein.
