SURVIVAL curves for Chlamydomonas reinhardii exposed to ionising radiation have an initial ‘shoulder’ region where sublethal damage is accumulated, followed by an exponential region where a further single event will result in cell death. When an initial dose is given to cells, sufficient to reduce the surviving fraction to the exponential region, followed by a series of graded doses given some hours later, cells recover from sublethal injury inflicted by the first dose, as shown by the return… CONTINUE READING
