Verified step by step guidance1
Understand the structure of a chromosome: Chromosomes consist of two sister chromatids joined together at a region called the centromere.
Review the phases of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase. Each phase has distinct characteristics and roles in cell division.
Focus on the role of sister chromatids: During mitosis, sister chromatids are crucial for ensuring that each daughter cell receives an identical set of chromosomes.
Identify the phase where sister chromatids are attached: In metaphase, sister chromatids are aligned at the cell's equatorial plane, still attached at the centromere, preparing for separation.
Clarify the separation process: In anaphase, the sister chromatids are pulled apart toward opposite poles of the cell, indicating that they are no longer attached at the centromere.
