Unusual mechanism of DNA synthesis could explain genetic mutations: Researchers have discovered the details of how cells repair breaks in both strands of DNA, a potentially devastating kind of DNA damage. When chromosomes experience double-strand breaks, cells utilize their genetically similar chromosomes to patch the gaps via a mechanism that involves both ends of the broken molecules. To repair a broken chromosome, a unique configuration of the DNA replication machinery is deployed.
