when hl-60 cells were separated by elutriation centrifugation into fractions enriched in g1 , s phase , or g2 + m , we found only differences in the amount of nucleotides per cell ( g2 + m greater than s phase greater than g1 ) corresponding with the increase in cell volume but not in the qualitative composition of the nucleotides .
