Which of these are NOT one of the three requirements for a successful cell cycle?

The cell cycle consists of a series of phases that cells go through in order to grow and divide. The phases include G1 (first gap), S (synthesis), G2 (second gap), and M (mitosis). For a cell cycle to be successful, there are certain key requirements.

One of the fundamental principles of the cell cycle is that the S phase, where DNA is replicated, must occur before the M phase, which involves the actual division of the cell. This sequence ensures that when the cell divides, each daughter cell receives a complete set of chromosomes.

Furthermore, cells must be responsive to checkpoint controls, which are mechanisms that monitor the integrity of the cell's DNA and regulate the progression of the cell cycle. These checkpoints help to ensure that a cell does not proceed to division unless it is ready, preventing the propagation of errors.

Balanced growth and division are also essential for maintaining healthy cell populations, as they ensure that cells replicate appropriately and maintain their functions.

In contrast, the notion that M phase precedes S phase contradicts the base sequence of the cell cycle. For the cell cycle to function properly, S phase must occur first, as it is when the genetic material is duplicated in preparation for cell division. Therefore, stating that
