Scientists capture first-ever atomic view of key genetic processes

Using a 3-D visualization method called X-ray crystallography, Song Tan, associate professor of biochemistry and molecular biology has built the first-ever image of a protein interacting with the nucleosome -- DNA packed tightly into space-saving bundles organized around a protein core. The research, performed at the Penn State Center for Eukaryotic Gene Regulation of the Huck Institutes, is expected to aid future investigations into diseases such as cancer.
