A. It does not alter the cell cycle.Wrong
B. It arrests cells before the restriction point. Possible
C. It arrests cells before the G1/S transition point. Possible
D. It arrests cells during S phase. Wrong
E. It arests cells before the G2/M transition point. Wrong
F. It arrests cells during M phase. Wrong
G. It accelerates the transition of the cells through G0 and induces arrest in G1. Wrong Arrest in G1 is possible, but the rate of the process (acceleration) cannot be determined in this experiment.
