While mrna strands are being created a sequence is sometimes miscopied. what is the best possible outcome for the cell should this take place?

The cell should immediately undergo apoptosis. which means cell death. i believe this should be the answer because the cell cycle regulates a cell's dna making sure everything is fine. if the cell cycle's checkers detect anything wrong it will immediately shut down the cell's formation in order to make sure they healthy cells are unaffected by the cell with the problem.
