the necessity for their combined action in dna repair in m. luteus is shown by : ( a ) reactivation of ultraviolet-damaged phix174 rfi dna in incision-defective hosts after in vivo treatment with both enzymes , ( b ) correlation between survival after ultraviolet irradiation and the level of the two enzymes , and ( c ) increased levels of repair synthesis after ultraviolet irradiation of toluenized cells db-400 with wild type correndonuclease levels when compared with the transformant db-200 and the mutant db-7 , which lack one or both enzymes .
