Figure 2

Rifampicin (Rif) resistance assay for AID-mediated cytidine deamination in UNG-deficient BW310 E.coli. The graph shows the mutation frequency (defined as the frequency of Rif-resistant clones) of individual starting colonies from E.coli transfected with the empty vector or plasmids expressing wt AID, K3 or lysineless deltaK. Median values ± SD are indicated in the graph.
