WebVariation of flagellar antigens analogous to that observed in Salmonella was observed when E. Coli strains were transduced with the hybrid lambda. By using the lambdaH2rh1 hybrid to program protein synthesis in UV-irradiated cells, the synthesis of a polypeptide was correlated with rh1 gene product activity.
