4. Short response (2 sentences max, 6pts each) A. Many yeast species have only one cyclin-dependent kinase (Cdk), which activates protein targets that drive events in multiple phases of the cell cycle. Why doesn't this Cdk activate G1-, S-, G2-, and M-phase proteins all at the same time? B. Please describe how cell death by apoptosis can play a beneficial role in the body's healthy growth. C. For a cell starting in G1, place the following cell cycle events in...
