Answer:
The correct answer would be - CDK inhibitors.
Step-by-step explanation:
Removing the CDK inhibitors in nonproliferating cells can reactivate the cell cycle that can be useful in various cell and tissue repair and also in cell replacement therapies.
These cells are depends on the parent cells that are able to divide so that the daughter cells are limited to the same cell lineage. If CDK inhibitors are removed from the cells can help in proliferating the cells as the cyclin B will be binding to the CDK1 that helps in cell cycle by rising Cyclin B - CDK complex.
Thus, the correct answer is - CDK.
