abstract：:When ultraviolet-irradiated bacteriophage T4 is assayed at plating temperatures ranging from 20 degrees to 40 degrees, its survival increases at the higher temperatures. This "thermal rescue" requires an intact WXY system but not the denV pyrimidine dimer excision system. Mutation rates decrease with increasing temper...
