Understand that the cell cycle is a series of phases that cells go through to grow and divide. It consists of two main stages: Interphase and M phase (Mitotic phase).
Interphase is the phase where the cell prepares for division. It includes three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During G1, the cell grows and performs its normal functions. In the S phase, DNA replication occurs, and in G2, the cell continues to grow and prepares for mitosis.
M phase, or Mitotic phase, is where the cell actually divides. It includes mitosis and cytokinesis. Mitosis is further divided into stages: prophase, metaphase, anaphase, and telophase, where the chromosomes are separated into two new nuclei.
Cytokinesis is the final part of the M phase, where the cytoplasm divides, resulting in two separate daughter cells.
Recognize that the correct answer to the problem is Interphase and M phase, as these encompass the entire cell cycle, including preparation, division, and completion of cell division.
