Passage of cells from G1 through R to S depends on the interaction of various signal molecules, proteins and enzymes which regulate the cell cycle.  Imagine I have just induced a mutation in a cell line which prevents the breakdown of the cyclin molecule we discussed.  Which of the following events do you predict will happen?  circle all that apply Select one or more: a. Uncontrolled cell replication may result b. Retinoblastoma protein will be continuously active c. The cells will be stuck in G1 phase d. The cells will begin to replicate their DNA e. Cyclin dependent kinase (Cdk) will be continuously active
