The SCF and APC/C complexes play important roles in cell cycle progression. Both complexes add groups to target proteins, which results in degradation of those proteins by the Checkpoint pathways are used to ensure that key events in a given cell cycle phase are completed before moving to the next phase. Cells use these pathways to monitor cell size, during cell cycle progression. and

Cell cycle checkpoints are surveillance mechanisms that monitor the integrity and fidelity of the major events of the cell cycle. Which of the following are true about cell cycle checkpoints? Select all that apply The M phase checkpoint examines whether all sister chromatids are correctly attached to the spindle microtubules Progression through checkpoints is determined by the activation of cyclin dependent kinases bound to cyclins The G2 checkpoint is also called the restriction checkpoint O If a cell passes the G1 checkpoint, it irreversibly commits to complete the whole cell cycle and divide

Describe the general conditions that must be met at each of the three main cell-cycle checkpoints.
Explain thoroughly: What are cell cycle checkpoints? Why are they important?
"Agent V" is the name of an anticancer (chemotherapy) drug. This drug works against cancer cells by inhibiting the formation of microtubules in sensitive cells. Consider a cell that is sensitive to agent V (in other words, agent V is effective at stopping growth of this cell). Based on this information, agent V would cause the cell to be frozen at which of the major cell cycle checkpoints (G1, G2 or M checkpoint)? Explain your answer in 2- 4 sentences.
Briefly outline the events that control the progression of cells through the G2/M checkpoint in the cell cycle.
During cell division cycle, cells need to monitor the process of DNA replication and segregation of replicated DNA so that these processes are error-free. Some potential errors that could occur include incomplete DNA replication, DNA damage in genome, and uneven separation of replicated genome. These mechanisms that cells used to monitor these processes are referred as the "cell cycle checkpoint, which can control specific Cdk activity to regulate the progression of cell cycle. For the following checkpoint mechanisms, indicate which Cdk activity is attenuated? Also indicate one of the key proteins or protein complexes involved in the following checkpoints. a) DNA damage checkpoint during S-phase b) Mitotic checkpoint during M-phase
The cell cycle control system is a cycling set of molecules in the cell that triggers and coordinates key events in the cell cycle. This is all controlled by growth factors. a) Identify the major checkpoints in a cell and its function. b)Explain the role of the growth factor.
