Question

what can result from improper regulation of the cell cycle? *
apoptosis
cancer
control checkpoints
mitosis without a prophase

Explanation:

The cell cycle is tightly regulated to ensure proper cell division. When regulation fails, cells can divide uncontrollably, which is a hallmark of cancer. Apoptosis is programmed - cell death and not a result of improper cell - cycle regulation in this context. Control checkpoints are part of the normal cell - cycle regulation system, not a result of its malfunction. Mitosis without prophase is not a typical consequence of improper cell - cycle regulation.
