It is estimated that over 30,000 lesions in the DNA are generated per cell per day. In S-phase, lesions in the DNA can stall replication, which can lead to secondary lesions such as DNA double- strand breaks. The DNA damage tolerance (DDT) network enables replication to be continued in the presence of …
