Table 2. Viability of 8-amino-dG containing M13 in E.coli^a.

Experiment no.b	Relative survival
	Control (%)		8-amino-dG (%)
	–SOS	+SOSc	–SOS	+SOSc
1	100	100	71	93
2	100	100	135	130
3	100	100	93	72
Average	100	100	100	98

^aViability (%) was determined by comparing the number of plaques from the 8-amino-dG containing DNA with that of the control genome (assumed to have 100% viability).

^bEach experiment refers to a separate construction of the control and the adducted genomes.

^cSOS was induced by UV irradiation at 20 J/m² as described by Bacolod et al. (24).
