The effect of overproduction of MMR proteins on growth-dependent and adaptive reversion of the episomal Lac− allele. The results are the mean number of Lac+ colonies per day appearing on Day 2 (white). and Days 3–5 (gray) after plating on lactose minimal medium, determined from 3 to 4 cultures of each strain. Each strain carried both a pACYC- and a pBR-derived plasmid; the genes on the plasmids are listed to the left of the graph. Error bars are ±S.E., and in some cases are too small to be seen. Plasmids carrying MMR proteins were obtained from M.G. Marinus [2,6].
