Degradation of Escherichia Coli DNA Synthesized after Ultraviolet Irradiation in the Absence of Repair

Summary DNA degradation in Escherichia coli uvrA recA bacteria exposed to a low dose (0·07 J/m2) of ultraviolet radiation was studied. A considerable amount of the newly-synthesized DNA, which contains gaps opposite pyrimidine dimers, is broken down. In contrast, parental, dimer-containing DNA is re...

Zusammenfassung:	Summary DNA degradation in Escherichia coli uvrA recA bacteria exposed to a low dose (0·07 J/m2) of ultraviolet radiation was studied. A considerable amount of the newly-synthesized DNA, which contains gaps opposite pyrimidine dimers, is broken down. In contrast, parental, dimer-containing DNA is resistant to radiation-induced degradation.
