Bacteria with defective rho factors suppress the effects ofN mutations in bacteriophage λ

A prediction based on the model forN-gene function of bacteriophage λ proposed by Roberts (1971) is confirmed by showing that a λN − double mutant is able to grow in strains ofE. coli with defective rho transcription termination factors. The burst sizes for λN − in these strains range from 5 to 24% the burst sizes for λN + in the same strain. This low level… CONTINUE READING
