Irradiation of mammalian cells to damage DNA will usually cause them to stop dividing and arrest at the G1/S checkpoint. Place the following events in the order. halt of cell cycle at G1-S transition translation of p21 mRNA stabilization and activation of p53 protein binding of p21 protein to G1/S-Cdk and S-Cdk P53- regulated transcription of p21 > > > >
