|
If DNA is damaged during the cell cycle, why does it need to be repaired before completing the cell cycle?
|
|
So the cell can undergo apoptosis
|
|
|
So healthy daughter cells can be produced and grow
|
|
|
So the cell can shrink
|
|
|
So the cell can become specialized
|
Explanation:
Detailed explanation-1: -The types of DNA lesion and the checkpoint pathways that are activated in response to DNA damage influence the DNA-repair pathways according to the cell-cycle phase. Failure to coordinate DNA repair with cell-cycle progression can cause genome instability, cell death and cancer.
Detailed explanation-2: -WEE1 arrests cells in the G2 phase of the cell cycle, allowing cells to repair DNA before proceeding into mitosis.
