AB  - Mutants of Salmonella typhimurium containing 1 to 2% of wild-type ribonuclease I activity were isolated. The rns mutation had no effect on the polarity of mutations in the S. typhimurium histidine operon. Even in the presence of an rns mutation, it was not possible to obtain strong suppressors of the polarity of two polar mutations in the his operon.
