Efficiency of NCO events with unidirectional versus bidirectional hDNA in the repaired plasmid allele.

All strains are mlh1Δ. Mean plasmid-repair, CO and NCO efficiencies were determined as in Table 1. The position of hDNA was determined by sequencing individual NCO events; proportions of unidirectional and bidirectional hDNA were derived using only those transformants in which hDNA was detected. Asterisks indicate a significant difference when compared to WT (p<0.05).
