Textbook Question
The interphase of the cell life cycle is divided into
(a) Prophase, metaphase, anaphase, and telophase
(b) G0, G1, S, and G2
(c) Mitosis and cytokinesis
(d) All of these
Verified step by step guidance1
Understand that the cell life cycle consists of different phases, including interphase and mitotic phase.
Recall that interphase is the period when the cell prepares for division and is not actively dividing; it includes phases where the cell grows and DNA is replicated.
Identify the phases of interphase: G0 (resting phase), G1 (first gap phase), S (synthesis phase where DNA replication occurs), and G2 (second gap phase).
Recognize that prophase, metaphase, anaphase, and telophase are stages of mitosis, not interphase.
Conclude that the correct division of interphase is represented by G0, G1, S, and G2 phases.

Here are the essential concepts you must grasp in order to answer the question correctly.
Cell Cycle Phases
The cell cycle consists of a series of stages that a cell goes through to grow and divide. It includes interphase (where the cell prepares for division) and the mitotic phase (where the cell actually divides). Understanding these phases is essential to distinguish between different parts of the cycle.

Introduction to the Cell Cycle
Interphase Subdivisions (G0, G1, S, G2)
Interphase is the longest phase of the cell cycle, divided into G0 (resting phase), G1 (cell growth), S (DNA synthesis), and G2 (preparation for mitosis). These stages are critical for cell growth and DNA replication before mitosis begins.

Mitosis and Cytokinesis
Mitosis is the process of nuclear division, consisting of prophase, metaphase, anaphase, and telophase, followed by cytokinesis, which divides the cytoplasm. These stages occur after interphase and are responsible for producing two identical daughter cells.
