From: Split MutT prevents the mutator phenotype of mutT-deficient Escherichia coli

Suppression of spontaneous mutation by split MutT expression in mutT cells. Each dot represents the rpoB mutant frequency obtained from a single colony. The median values are shown in the upper part. Their relative values, calculated using the mean of rpoB mutant frequencies of Mu95 + MBP and GST + 96tT as 1.0, are also shown in parentheses. The 95% confidence interval values are 1.4 × 10–7 – 2.1 × 10–6, 1.6 × 10–7 – 4.6 × 10–7, 1.1 × 10–8 – 1.2 × 10–7, and 1.8 × 10–7 – 3.1 × 10–7 for Mu95 + MBP, GST + 96tT, Mu95 + 96tT, and Mu95 (A53) + 96tT, respectively.
