Figure 1.

Recovery of UV-inhibited RNA synthesis. RNA synthesis was measured as the relative incorporation of ³H-uridine in 5 J/m²-irradiated cells compared with unirradiated cells (100%) (average values of three experiments). MRC5 (■), CS1AN (●), E61AN transfectant (CS1AN cells carrying the ERCC6 gene) (▴). The relative transcription capacity of nuclear extracts from UV-irradiated cells is indicated as well (average values of two experiments): MRC5 (□), CS1AN (○). Bars represent standard errors.
