FIG. 6.

(A) Molecular characteristics of deletions in wild-type and recA-deficient strains. Nucleotides of the original I-SceI site are in blue, resected nucleotides are indicated by a line, and nucleotides of microhomology are boxed. To the right of the sequences is the number of events observed for each type of microhomology in wild-type and recA strains, with the number of deleted nucleotides in parentheses. (B) Statistical analysis of microhomology usage and deletion size in wild-type and recA-deficient strains. WT, wild type.
