Growth of parental, WT-RacB, and V12-RacB cells. Equal numbers of cells from each cell line were added to wells of a microtiter plate. Cells from two wells were taken every 10 to 14 h to determine the average cell density. Parental Ax4 cells have an 11-h generation time, while V12-RacB cells stopped growing 36 h after folic acid removal. WT-RacB cells had a slightly lower growth rate.
