Verified step by step guidance

Understand the cell cycle phases: The cell cycle consists of interphase (which includes G1, S, and G2 phases) and the mitotic phase (which includes prophase, metaphase, anaphase, and telophase).

Identify the role of centrosomes: Centrosomes are crucial for organizing microtubules and are involved in the formation of the mitotic spindle during cell division.

Focus on the mitotic phase: During the mitotic phase, the cell undergoes division, and the centrosomes play a key role in this process.

Examine prophase: In prophase, the chromatin condenses into visible chromosomes, and the centrosomes begin to move to opposite poles of the cell, starting the formation of the mitotic spindle.

Conclude with centrosome separation: The separation of centrosomes is initiated in prophase, as they move apart to opposite ends of the cell to facilitate chromosome alignment and separation in later stages of mitosis.
