Verified step by step guidance

Understand the stages of mitosis: Mitosis is divided into several phases, including prophase, prometaphase, metaphase, anaphase, and telophase. Each phase has distinct events that occur.

Identify the events of prophase and prometaphase: During prophase, the chromosomes condense and become visible, the mitotic spindle begins to form, and the nuclear envelope starts to break down. Prometaphase involves further breakdown of the nuclear envelope and attachment of spindle fibers to chromosomes.

Recognize the event that occurs in anaphase: Sister chromatids separate during anaphase, not during prophase or prometaphase. This is a key event that distinguishes anaphase from the earlier phases.

Compare the given options with the events of prophase and prometaphase: Review each option and determine which event does not align with the typical occurrences during prophase and prometaphase.

Conclude which event does not occur during prophase and prometaphase: Based on the understanding of mitotic phases, identify that the separation of sister chromatids is the event that does not occur during prophase or prometaphase.
