title: New glimpses of an old machine.
abstract: Two recent studies illustrate the ability of the Mre11/Rad50 DNA repair complex to bind and connect DNA ends. Specific stimulation of DNA ligase IV-mediated end-joining by Mre11 complexes from S. cerevisiae suggests the possibility of a direct role in nonhomologous end-joining in eukaryotic cells.
