Figure 2 From: The role of upstream sequences in selecting the reading frame on tmRNA Analysis of -1 triplet mutant activity. The hybrid bacteriophage λimmP22 c2-dis only forms plaques on cells expressing active tmRNA [3, 19]. Data are expressed as efficiency of plating (EOP) with wild-type tmRNA taken as EOP = 1. The del-ssrA mutant lacks tmRNA. Error bars represent the standard deviation of three independent experiments.Back to article page
