Repair of radiation-induced strand breaks as related to the inducible inhibitor of postirradiation DNA degradation.
The repair of radiation-produced single-strand breaks observed under alkaline conditions is very apparent in cells which possess an inducible inhibitor of postirradiation DNA degradation. Previous induction of the inhibitor with ultraviolet light increases the amount of repair. In those cells which are genetically not inducible there is no increase following ultraviolet irradiation.
