Biological process

error-free PRR

The conversion of DNA-damage induced single-stranded gaps into large molecular weight DNA via processes such as template switching, which does not remove the replication-blocking lesions but does not increase the endogenous mutation rate.

error-free replication restart

Note that 'error-free' does not mean that literally zero errors occur during DNA synthesis, but that the error rate is low, comparable to that of DNA synthesis during replication.
