Multiple Choice
What is the purpose of cell cycle checkpoints?
A
To coordinate a cell’s specialization for its role in particular tissues.
B
To prevent the cell from pausing the cell cycle when problems are detected.
C
To ensure that cells containing errors in their DNA do not undergo apoptosis.
D
To coordinate movement of vesicles through the cell.
E
To ensure that a cell only proceeds to the next phase in the cell cycle if it is ready.
검증된 단계별 안내1
Understand the concept of the cell cycle: The cell cycle is a series of phases that a cell goes through to divide and produce new cells. It includes phases such as interphase (G1, S, G2) and mitotic phase (M).
Learn about cell cycle checkpoints: Checkpoints are control mechanisms in the cell cycle that ensure the cell is ready to proceed to the next phase. They help maintain the integrity of the cell's genetic material.
Identify the main checkpoints: The primary checkpoints are the G1 checkpoint, G2 checkpoint, and the M checkpoint. Each checkpoint assesses different criteria to ensure the cell is prepared for the next phase.
Explore the purpose of checkpoints: Checkpoints prevent the progression of the cell cycle if there are errors or damage in the DNA, ensuring that only healthy cells divide. This helps prevent mutations and cancer.
Clarify the correct answer: The purpose of cell cycle checkpoints is to ensure that a cell only proceeds to the next phase in the cell cycle if it is ready, thereby maintaining cellular integrity and function.
