Figure 5From: Low-mutation-rate, reduced-genome Escherichia coli: an improved host for faithful maintenance of engineered genetic constructsComparison of the mutational spectra of various strains. The bar graph shows the distribution of cycA mutation types, detected by PCR analysis. The share of deletions (too low to be visible) is 1.6, 2.4, and 4.3% of the total mutations in MG1655, MDS42, and MDS42pdu, respectively. No deletions were detected in BL21(DE3).Back to article page
