摘要: The precise replication of the genome and continuous surveillance its integrity are essential for survival avoidance various diseases. Cells respond to DNA damage by activating a complex network so-called checkpoint pathways delay their cell-cycle progression repair defects. In this review we integrate findings on emerging mechanisms activation, signalling spatio-temporal organization intra-S-phase DNA-damage impact machinery, discuss biological significance.
