...protein. To test that theory, the Duke team made artificial strings of glutamines,either 20 glutamines, found in normal proteins, or 60 glutamines, foundin the mutant proteins. They then mixed these glutamine strings with brainproteins to see what proteins bound. They found that one brain protein,glyceraldehy...Freshwater Sponges May Pose Threat To Zebra Mussels
