WebA number of surveillance systems exist that interrupt cell cycle progression when damage to the genome or spindle is detected, or when cells have failed to complete an event (Weinert and Hartwell 1988). These surveillance systems are termed checkpoints and have been given an empirical definition. When the occurrence of an event B is dependent … Webin this video, we're going to introduce the cell cycle checkpoints.
