Abstract
Abstract. Irradiation of closed circular phage Λ DNA in vivo at 365 nm results in the induction of single‐strand breaks and alkali‐labile lesions at rates of 1.1 × 10‐14, and 0.2 × 10‐14/dalton/J/m2, respectively. The sum of the induction rates is similar to the rate of induction of single‐strand breaks plus alkali‐labile lesions (1 × 10‐14/dalton/J/m2) observed in the E. coli genome. Postirradiation incubation of wild‐type cells in buffer results in rapid repair of the breaks (up to 80% repaired in 10 min). No repair was observed in a DNA polymerase I‐deficient mutant of E. coli.
