title: Rejoining of radiation-induced single-strand breaks in deoxyribonucleic acid of Escherichia coli: effect of phenethyl alcohol.
abstract: Single-strand breaks in deoxyribonucleic acid of Escherichia coli B/r cells exposed to 20 krads of gamma radiation could be rejoined by incubation of irradiated cells in growth medium. In the presence of 0.25% phenethyl alcohol, this repair was completely inhibited although deoxyribonucleic acid and protein syntheses were suppressed only partially.
