QUESTION 31 You are a new PhD student in the lab of Dr. Adenine and start noticing that many of the cells you are studying for your project have two centrosomes. You realize that a defect during one specific phase of the cell cycle could explain this double-centrosome phenotype. A defect during which phase is most likely to be the culprit? G1 phase. Metaphase. G2 phase. O Interphase.
QUESTION 17 Which of the following events describe the mechanism of a cell cycle checkpoint? (choose more than one if applicable) If you really want to challenge yourself, figure out which cell cycle checkpoint is described by each of your choices. Questions about this topic are commonly missed on the unit 3 exam! U A Cdk is phosphorylated, turning it off. This prevents the cell from entering the next phase before it is ready. A ubiquitin ligase is activated to target a Cdk for destruction. Since the Cdk is destroyed, it cannot be active and therefore cannot cause entry into the next phase of the cell cycle. A Cdk inhibitor protein is transcribed and translated when it otherwise wouldn't be, which turns off a Cdk and prevents the cell from entering the next phase before it's ready. A ubiquitin ligase is inhibited, preventing the proteolysis of proteins that must be destroyed in order for the cell to advance to the next step in the cell cycle. One of these proteins that is not destroyed…
