Abstract

Monkey kidney cells, either untreated or pretreated with UV-light at 254 nm or mitomycin C, were transfected 24 hours later with the intact or UV-irradiated DNA from the thermosensitive tsB201 simian virus 40 mutant unable to grow at 41 degrees C. The survival of the viral progeny obtained from the UV-irradiated DNA is increased in pretreated cells compared to the survival of the viral progeny obtained in untreated cells. Irradiation of the viral DNA enhances the reversion frequency of the viral progeny towards a wild type phenotype able to grow at 41 degrees C. Pretreatment of the cells with UV or mitomycin C does not increase the reversion frequency.
