Failure of accumulation of cellular RNA in hamster cells stimulated to synthesize DNA by infection with adenovirus 2

AF8 cells are temperature-sensitive mutants of the cell cycle derived from
baby hamster kidney (BHK) cells which arrest in the G1 phase when incubated
at the nonpermissive temperature. RNA accumulation was studied in these
cells by flow cytofluorimetry following serum stimulation or adenovirus 2
infection. Serum stimulation caused an increase in the amount of RNA per
cell, which reached a maximum in S and G2 cells, as repeatedly reported in
the literature. However, adenovirus 2 infection caused a fraction of cells
to enter S phase without any concomitant increase in the amount of RNA per
cell.
