Verified step by step guidance

Understand the role of the centromere: The centromere is a region on a chromosome where sister chromatids are held together. It plays a crucial role during cell division, particularly in mitosis and meiosis.

Identify the phase of cell division: In prophase, the chromosomes condense and become visible under a microscope. The sister chromatids are joined at the centromere.

Recognize the function of the centromere during prophase: During prophase, the centromere is the point where the sister chromatids are attached to each other, preparing for alignment and separation in later stages of mitosis.

Differentiate between the phases of mitosis: Metaphase is when chromosomes align at the cell's equatorial plane, anaphase is when sister chromatids separate, and telophase is when the cell prepares to divide into two.

Conclude the correct function of the centromere: Based on the understanding of cell division phases, the centromere's role in prophase is to attach sister chromatids to one another, which is crucial for their proper segregation during cell division.
