Abstract
Damage-inducible DNA replication (iSDR) was followed in UV-irradiated E. coli uvr+ and uvr B5 cells. Owing to the inhibition of dimer excision in the former (caused by the metabolic treatment), both contained similar amounts of unexcised dimers. Since the iSDR took place in uvr+ but not in uvr B5 cells, it is concluded that the uvr system can tolerate unexcised dimers through the recombinogenic iSDR.
