Brandt Eichman and Walter Chazin, professors of biochemistry, have worked together to provide a better understanding of how exactly DNA replication is initiated in eukaryotes. Using Vanderbilt's state-of-the-art instrumentation in the Center for Structural Biology's Cryo-Electron Microscopy Facility, Eichman, Chazin, and their colleagues provided detailed visualizations of a multi-functional protein in action, which sheds light on how DNA replication is initiated in humans.
