1st 3-D molecular view of key genetic processes

August 26, 2010 - In a landmark study to be published in the journal Nature, scientists have been able to create the first picture of genetic processes that happen inside every cell of our bodies. Using a 3-D visualization method called X-ray crystallography, Song Tan, associate professor of biochemistry and molecular biology at Penn State, 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 is expected to aid future investigations into diseases such as cancer.
