Question

Select the correct answer.

A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?
A.
The cell divided and created two cells with repaired DNA.
B.
The cell couldn’t divide, and cell division stopped.
C.
The cell died before it could complete division.
D.
The cell divided and created two nonidentical cells.
E.
The cell continued to divide uncontrollably to create more damaged cells.

I am just giving out points; have way too many. :)

Answer 1

The likely consequence of a G2 checkpoint failure in a cell with damaged DNA is uncontrollable division and creation of more damaged cells, a pathway that can lead to cancer.

Step-by-step explanation:

If the G2 checkpoint failed to work in a model cell with damaged DNA, the likely consequence is that the cell continued to divide uncontrollably to create more damaged cells. This is because the G2 checkpoint is responsible for preventing a cell with DNA damage from entering mitosis. When this checkpoint is not functioning correctly, cells with mutated or damaged DNA can proceed to divide, potentially leading to tumor growth if the cells contain oncogenes or non-functional tumor-suppressor genes like p53. This can cause the accumulation of mutations and unregulated cell division, typical of cancer cells.
