Which of the following best describes what occurs during interphase in the cell cycle?

• A. The nuclear envelope breaks down and spindle fibers form.
• B. Cytokinesis divides the cytoplasm into two distinct cells.
• C. The cell grows, replicates its DNA, and prepares for mitosis.
• D. Chromosomes are separated into two daughter cells.

Answer: (C)

Verified step by step guidance

1. Understand that interphase is the longest phase of the cell cycle, occurring before mitosis and cytokinesis.
2. Learn that interphase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
3. During the G1 phase, the cell grows and performs its normal functions, preparing for DNA replication.
4. In the S phase, DNA replication occurs, ensuring that each daughter cell will have a complete set of genetic material.
5. During the G2 phase, the cell continues to grow and prepares for mitosis by synthesizing proteins and organelles needed for cell division.
