Degradation of [3H]thymidine-labelled T4 2− DNA in UV-irradiated cells
| Strain | Relevant genotype | % Acid-soluble material from cells irradiated with the following UV dose (J/m2)a:
|
|||
|---|---|---|---|---|---|
| 0 | 27 | 54 | 135 | ||
| AB1157 | Wild-type | 48.7 (±1.2) | ND | 41.5 (±1.0) | 34.3 (±0.5) |
| WA618 | uvrA277::Tn10 | 46.8 (±1.6) | 44.3 (±4.4) | ND | 45.7 (±1.3) |
| WA485 | polA1 | 52.6 (±2.0) | 17.7 (±5.8) | ND | 9.7 (±0.2) |
a Log-phase cells were irradiated with the UV doses indicated and aerated at 30°C for 90 min before infection with labelled T4 2− phage at 30°C. The amount of cold acid-soluble products was determined 60 min after infection. The data are means from two independent experiments given with the range. ND, not determined.
