Powerful X-ray technology developed at DOE national laboratories is revealing new insights into diseases ranging from Alzheimer's to swine flu. This

X-ray crystallography [kris-tl-OG-ruh-fe] has been used for all EXCEPT which of the

following?

W) Revealing the structures of diseased and disease-causing molecules

X) Creating three-dimensional maps of mutated enzymes

Y) Producing scattered, low intensity X-ray beams to surround the surface of the molecules

Z) Allowing medical researchers to develop drugs to prevent mutated enzymes from triggering cancer cells
Y) PRODUCING SCATTERED, LOW INTENSITY X-RAY BEAMS TO SURROUND THE SURFACE OF THE MOLECULES
