A new recombination control mechanism plays an essential role in genome stability

A new process that will control homologous recombination by eliminating potentially toxic intermediaries has just been demonstrated. This work, carried out jointly by the CEA’s Laboratory for the Study of DNA Repair (DRR, Fontenay-aux-Roses) and the Department of Molecular Microscopy of the Gustave Roussy Institute (IGR) (Villejuif), is published in the journal Nature dated 15 May 2003.
