Genetic analysis of histidine independent (His +) revertants induced by ultraviolet light in the his-4 E. coli strain ABl157 was carried out: 83% carried ochre (UAA) suppressor m~atations and 17% carried back mutations to his + or (intragenic?) suppressors not detectably separable from his-4. Using
