Questions & Step-by-Step Solutions
Which checkpoint is crucial for preventing the division of cells with damaged DNA?
Step 1: Understand that cells go through a cycle called the cell cycle, which includes different phases.
Step 2: Recognize that during the cell cycle, there are checkpoints that monitor the condition of the cell.
Step 3: Identify the G2 checkpoint, which occurs after the DNA has been copied but before the cell divides.
Step 4: Know that the G2 checkpoint checks if the DNA is damaged or if there are any errors in the DNA.
Step 5: Realize that if the DNA is found to be damaged, the G2 checkpoint will stop the cell from dividing.
Step 6: Conclude that the G2 checkpoint is crucial because it prevents cells with damaged DNA from continuing to divide, which helps maintain healthy cells.
