Scientists identify how cells make choice between various mechanisms to repair DNA

When DNA in the cell nucleus gets damaged, our cells can resort to a variety of repair mechanisms. A recent study published in 'Nature Cell Biology', to which scientists from Helmholtz Zentrum Muenchen made major contributions, elucidates the molecular basis by which a cell makes the choice between these repair mechanisms.
