(A) Photograph of agarose gels containing electrophoretically separated low molecular weight DNA fractions from mock-infected cells or cells infected with d120 mutant and stained with ethidium bromide. Subconfluent Vero (A) or HeLa cells (B) were either left untreated or treated with 50 μM z-VAD-fmk or 100 μM Ac-DEVD-CHO (Vero cells) or treated with 100 μM Ac-DEVD-CHO (HeLa cells) and then exposed to 1.5 M sorbitol or infected with 10 pfu of d120 mutant per cell and harvested at 5 hr after treatment and 24 hr after infection, respectively. Samples were processed as described in the legend to Fig. 2.
