Figure 5. Mutations within Unsorted and Sorted sIgM(–) cells.

Distribution of nucleotide substitutions within genomic sequences from unsorted AID^RψV^– cells and within cDNA sequences from sorted IgM(–) AID^RψV^– cells. The numbers of mutations are counted for every 50 bp, and are shown together with the corresponding physical maps of the light chain genomic locus or the cDNA sequence.
