Body cell 'Q' had a normal mitotic index of 9.3%. However, scientists measured an increase in the mitotic index to 22.7%. This increase could NOT be explained as....

• a normal increase in cell division due to the cell increasing it's mitotic rate

• an abnormal increase in cell division due to mutations in the DNA

• a normal increase in cell division due to damage/death of nearby cells

• an abnormal increase in cell division due to the cell 'blowing through' its checkpoints
