Verified step by step guidance
1
Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase. Each phase has distinct events that occur in the cell.
Identify the role of centrioles: Centrioles are cylindrical structures that play a crucial role in cell division by helping to organize the mitotic spindle, which is essential for separating chromosomes.
Focus on prophase: During prophase, several key events occur, including the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the beginning of spindle formation.
Recognize the movement of centrioles: In prophase, centrioles begin to move apart towards opposite poles of the cell. This movement is critical for the formation of the mitotic spindle.
Conclude with the correct phase: Based on the understanding of mitosis and the role of centrioles, the phase during which centrioles begin to move apart is prophase.
