Fig. 6. The rapid growth to L4 stage of wrn-1(RNAi) worms is unaffected by -irradiation. Wild-type N2 worms were microinjected with dsDNA derived from Ce-wrn-1 cDNA. F1 progeny were irradiated with different dose (0, 10, 20 Gy) of -rays at the L1 larval stage and their growth to L4 stage was measured every twelve hours at 20°C. Over 150 F1 worms were used per measurement with two additional repetitions, and standard errors (s.e.m.) are shown by error bars.
