TABLE 1.
Frequency of chromosomal aberrations in UV-irradiated DT40 cellsa
| Cells | No. of chromosomal aberrations
|
||||
|---|---|---|---|---|---|
| Chromatid type | Chromosome type | Chromatid exchange | Total | Per cell ± SE | |
| Wild type | 3 | 11 | 4 | 18 | 0.36 ± 0.08 |
| REV1 | 3 | 9 | 5 | 17 | 0.34 ± 0.08 |
| UBMΔ | 5 | 19 | 3 | 27 | 0.54 ± 0.10 |
| Δrev1 | 10 | 29 | 1 | 40 | 0.80 ± 0.13 |

Fifty metaphase spreads were analyzed for each cell line. The number of total aberrations per cell ± SE was calculated as x/N ± √x/N. Note that the results for wild-type, REV1, and Δrev1 cells are from reference 7.
