Popis	To monitor apoptotic changes, we followed several parameters including cell viability, DNA integrity and telomerase activity.Preapoptotic phase has been achieved by exposure of cells to 50mM cadmium for 3 days.At that time the cell culture retains more than 95% viability although the majority of DNA is fragmented into 50-200 kb.Integrity of DNA is reestablished within two days after cadmium removal suggesting that an efficient DNA repair process has occurred.In parallel, a significant increase of telomerase activity in cell extracts is observed.The data suggest an involvement of telomerase in plant chromosome healing in response to damage caused by genotoxic agents.
