The cell cycle: which of the following statements is correct?

The correct answer is A. The cell cycle is the process by which cells grow and divide to produce new cells. The cell cycle is the series of events that occurs in a cell leading up to its division into two daughter cells. It is divided into two main phases: interphase and the cell division phase. Interphase is the phase of the cell cycle during which the cell grows and prepares for division. The cell division phase is divided into two subphases: mitosis and cytokinesis. Mitosis is the process by which the cell's nucleus divides, and cytokinesis is the process by which the cell's cytoplasm divides to form two daughter cells. B. The cell cycle is the process by which cells become specialized to perform specific functions is incorrect because cell specialization, or differentiation, occurs during development, not during the cell cycle. C. The cell cycle is the process by which cells die and are replaced by new cells is incorrect because cell death and replacement are separate processes from the cell cycle. D. The cell cycle is the process by which cells repair themselves after damage is incorrect because repair of damaged cells is a separate process from the cell cycle.
