Effect of bleomycin treatment on Lys+ reversion frequency in diploid strains
| Strain | Lys+ revertant frequency (10−7)a
|
||
|---|---|---|---|
| Spontaneous | Plus bleomycin | Inducedb | |
| MLH1/MLH1 | 4.9 (3.6–7.2) | 13 (8.0–58) | 8.1 |
| MLH1/mlh1Δ | 52 (29–68) | 500 (410–580) | 450 |
Median for nine independent determinations, with 95% confidence limit in parentheses.
Revertant frequency after bleomycin treatment minus spontaneous revertant frequency.
