Final answer:
The correct answer is b) Mitosis is the phase where the cell's nucleus divides. DNA replication occurs during the S phase and not the G1 phase, cytokinesis follows mitosis, and the G2 phase is not a resting phase but a phase of continued growth and preparation for mitosis.
Step-by-step explanation:
The correct statement about the events of the cell cycle is b) Mitosis is the phase where the cell's nucleus divides.
The cell cycle is composed of interphase and the mitotic phase. Interphase itself includes three phases: G1, S, and G2. During the G1 phase, the cell grows and prepares for DNA replication but does not actually replicate the DNA. DNA replication occurs during the S phase, also known as the Synthesis phase. Following the completion of DNA replication, the cell enters the G2 phase where it continues to grow and prepares for mitosis. The G2 phase is not a resting phase but rather a stage of further preparation for cell division.
The mitotic phase follows interphase, consisting of mitosis and cytokinesis. In mitosis, the nucleus divides to ensure that the two daughter cells receive identical copies of the DNA. Cytokinesis, which generally occurs after mitosis, is the division of the cell's cytoplasm, completing the process of cell division.
