RNA synthesis rate was measured at different time points after UV irradiation in various xeroderma pigmentosum (XP) cells including complementation groups F and G. The RNA synthesis was assayed by measuring 3H-uridine incorporation. In normal cells, recovery of RNA synthesis was initiated at about 6 hr ager UV irradiation and reached to the same level as in unirradiated cells at 24hr after UV irradiation. By contrast, no such recovery was observed in group F,G XP cells.
