Which of the following statements best describes interphase?

• A. It is the shortest phase of the cell cycle, occurring immediately before cell division.
• B. It is the process by which the cytoplasm divides to form two new cells.
• C. It is the phase of the cell cycle where the cell grows, replicates its DNA, and prepares for mitosis.
• D. It is the stage during which chromosomes are separated into two daughter cells.

Answer: (C)

Verified step by step guidance

1. Understand the context of the question: The problem is asking for the best description of interphase, which is a key phase in the cell cycle. The cell cycle includes interphase and mitotic phases (mitosis and cytokinesis).
2. Recall the definition of interphase: Interphase is the phase of the cell cycle where the cell spends the majority of its time. It is not a part of mitosis but is crucial for preparing the cell for division.
3. Break down the activities during interphase: Interphase consists of three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During G1, the cell grows and performs normal functions. In the S phase, DNA replication occurs, and in G2, the cell prepares for mitosis by synthesizing proteins and organelles.
4. Eliminate incorrect options: The first option describes interphase as the shortest phase, which is incorrect because interphase is the longest phase of the cell cycle. The second option describes cytokinesis, which is the division of the cytoplasm. The fourth option describes mitosis, where chromosomes are separated into daughter cells.
5. Select the correct answer: The correct description of interphase is the third option: 'It is the phase of the cell cycle where the cell grows, replicates its DNA, and prepares for mitosis.' This aligns with the biological processes occurring during interphase.
