It has been found that the repair of single strand breaks is defective in the DNA replication mutants cdc8-1 and cdc8-3 of Saccharomyces cerevisiae both in permissive (23°C) and restrictive conditions (36°C). In permissive conditions we observed a significant delay in single strand break repair in a diploid strain HB7 (cdc8-1/cdc8-1), as compared with the wild-type strain. Under restrictive conditions no repair was observed, but rather degradation of MMS-damaged DNA occurred. It has been also found that the repair of single strand breaks in yeast is inhibited by cycloheximide but not by hydroxyurea.
