Temperature-sensitive (ts) mutations were isolated within a ribosomal protein gene (rpsL) of Escherichia coli K12. Mutations were mapped by complementation using various transducing phages and plasmids carrying the rpsL gene, having either a normal or a defective promoter for the rpsL operon. One of
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
