DNA Transactions at an Atomic Level

The genetic information encoded within DNA is copied, maintained, and decoded by protein machines. Our laboratory uses electron microscopy, X-ray crystallography, and other high-resolution structural and biochemical approaches to investigate the molecular details of how these proteins repair damaged DNA and maintain integrity of the genome during replication.
