Question

What will likely happen if all cell cycle checkpoints stop working?

O The cell will increase its cytoplasmic content.
The cell will undergo uncontrolled cell division.
O The cell will initiate biochemical processes for cell death.
O The cell will begin to break down and lose cell volume.

Answer 1

Answer:

O The cell will undergo uncontrolled cell division.

Step-by-step explanation:

Cell cycle checkpoints are crucial mechanisms that ensure that the cell progresses through the cell cycle in a regulated and controlled manner. These checkpoints monitor the completion of specific events during the cell cycle and halt the progression of the cycle if any errors are detected. If all of these checkpoints were to stop working, the cell would not be able to regulate its progression through the cell cycle. This could lead to uncontrolled cell division, which is a hallmark of cancer. Uncontrolled cell division occurs when cells divide rapidly and uncontrollably, leading to the formation of tumors. Therefore, the loss of cell cycle checkpoints is associated with an increased risk of cancer.

Answer 2

Answer:b

Explanation:the checkpoints make sure that their is no excessive uncontrollable cell division,therefore one of the mechanisms of cancer(neoplasia) is loss of checkpoint inhibition.

Nowadays many checkpoint inhibitors are available in market and serve as therapy for many cancers.
