Closely observing the multiplication of cells

Our cells must grow and divide optimally to ensure that our bodies functions properly. It is essential, however, that these processes are carefully controlled in order to prevent unrestrained proliferation that can lead to the formation of tumours. David Shore, a professor at the Faculty of Sciences, University of Geneva (UNIGE), Switzerland, and his team have uncovered a cellular factor that regulates the timing of DNA replication. This molecule, called Rif1, ensures that only a fraction of the origins of DNA replication is activated at specified times of the cell cycle.
