Verified step by step guidance

Understand the cell cycle: The cell cycle consists of interphase and the mitotic (M) phase. Interphase is the period of growth and DNA replication, while the M phase is where cell division occurs.
Identify the phases of interphase: Interphase is divided into three main phases: G1 phase (cell growth), S phase (DNA synthesis), and G2 phase (preparation for mitosis).
Recognize the role of the M phase: The M phase, or mitotic phase, involves the processes of mitosis and cytokinesis, where the cell divides into two daughter cells.
Differentiate between interphase and the M phase: Interphase is focused on cell growth and preparation for division, while the M phase is the actual division process.
Conclude which phase is not part of interphase: Since the M phase is involved in cell division and not in the growth and preparation stages, it is not part of interphase.
