DNA damage induces the recruitment of various protein kinases to the site of damage and activates the signaling pathway involved in cell-cycle arrest. In this process, a CKI binds and inactivates G1/S-Cdk and S-Cdk complexes, arresting the cell in G1. For which mechanism is the CKI responsible? A. p16 B. p19 C. p21 D. p27 E. p14

Instead of adding EGF to otherwise normal cells expressing normal HER1, you induce DNA damage. You observe that ATM activity is initially off, but rapidly increases and then becomes inactive again. You observe that the interaction between CFP-p21CIP + YFP-CDK goes from FRETOFF to FRETON to FRETOFF. Finally, the levels of T14 and Y15 phosphorylated CDK remain low the entire time. Which of the following most accurately pertains to these cells? A. Cells are in G1, activated the p53-independent DNA damage checkpoint and repaired the damage. B. Cells activated the p53-independent DNA damage checkpoint and repaired the damage. You can only determine they were not in G1 based on the information provided. C. Cells activated the p53-independent DNA damage checkpoint and did not repair the damage. You cannot determine the cell cycle phase these cells were in based on the information provided. D. Cells activated the p53-dependent DNA damage checkpoint and repaired the damage. The cells were likely in G1, but you cannot determine this unambiguously based on the information provided. E. Cells activated the p53-dependent DNA damage checkpoint and did not repair the damage. You cannot determine the cell cycle phase these cells were in based on the information provided.

Mammalian cells damaged by radiation usually stop dividing and arrest at a G1 checkpoint. The events that mediate this process occur in the following order: A) DNA damage, production of p21, inhibition of cyclin-Cdk, accumulation and activation of p53 B) DNA damage, accumulation and activation of p53, production of p21, inhibition of cyclin-Cdk complexes C) Inhibition of cyclin-Cdk complexes, accumulation and activation of p53, DNA damage, production of p21 D) Accumulation and activation of p53, DNA damage, production of p21, inhibition of cyclin-Cdk complexes E) None of the above
