Photo-reactivation after Division II

Abstract

IT was reported earlier that in a strain of Tetrahymena pyriformis grown in this laboratory the lethal effect of ultra-violet light could be photo-reactivated even after the irradiated individuals had divided once or twice1. There are several ways in which this phenomenon might be used to elucidate the lethal action of ultra-violet light. Many preliminary enquiries could be made; but it is particularly desirable to determine whether the observed response is a general characteristic or a special trait of the particular species and strain used.
