The function of apoptosis in the cell cycle is to destroy damaged or old cells. This programmed cell death helps maintain healthy tissue by eliminating cells that could potentially lead to issues such as cancer if they continue to divide.
There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesn’t stop. Summarize the function of apoptosis in the cell cycle.(1 point) Responses to allow the cell to rest before the cell cycle restarts to allow the cell to rest before the cell cycle restarts to repair damaged or old cells to repair damaged or old cells to destroy damaged or old cells to destroy damaged or old cells to facilitate cell reproduction before the cell cycle restarts

When mutated cells ignore checkpoints, they reproduce uncontrollably, forming tumors. During which stage of the cell cycle does the cell divide into two cells?(1 point) Responses M M G2 G2 G1 G1 S
The cell divides into two cells during the M (mitosis) stage of the cell cycle.
Some cells ignore cell cycle checkpoints and continue to grow and divide uncontrollably despite cellular or genetic damage. What disease may directly result from such behavior?(1 point) Responses emphysema emphysema cancer cancer anemia anemia diabete
The disease that may directly result from such behavior is cancer.
Summarize the function of checkpoints in the cell cycle.(1 point) Responses Checkpoints stop the cell cycle when errors are detected. Checkpoints stop the cell cycle when errors are detected. Checkpoints ready the cells for genetic material replication. Checkpoints ready the cells for genetic material replication. Checkpoints prepare the cells for organelle replication. Checkpoints prepare the cells for organelle replication. Checkpoints allow complete cells to bypass stages of the cycle.
The function of checkpoints in the cell cycle is to stop the cell cycle when errors are detected. These checkpoints help ensure that only healthy and properly functioning cells proceed to the next stage, preventing the propagation of damaged or unregulated cells.
A cell contains DNA damage that causes it to undergo apoptosis before reaching mitosis. This cell had twice the amount of DNA for a cell of this type. During which checkpoint did this cell trigger apoptosis?(1 point) Responses G1 Checkpoint cap g sub 1 Checkpoint G2 Checkpoint cap g sub 2 Checkpoint M Checkpoint cap m Checkpoint No checkpoint meets these criteria
This cell likely triggered apoptosis during the G2 Checkpoint. The G2 checkpoint assesses the integrity of DNA and ensures that any damage is repaired before the cell enters mitosis (M phase). If significant DNA damage is detected, the cell may undergo apoptosis to prevent issues down the line.
