During which phase do paired chromosomes line up between the centrioles?

During metaphase, paired chromosomes align at the cell's equatorial plane, also known as the metaphase plate. This alignment is essential for ensuring that the chromosome segregation happens accurately during the next phase, anaphase. Each chromosome is attached to spindle fibers that connect to the centrioles, which are specialized structures that help to organize and pull the chromosomes apart. This precise arrangement is crucial for maintaining genetic stability, as it ensures that each daughter cell receives an identical set of chromosomes after division.

In prophase, chromosomes condense and become visible, but they have not yet aligned. Anaphase involves the separation of the paired chromosomes as they are pulled toward opposite poles of the cell, and telophase is marked by the reformation of the nuclear envelope around each set of separated chromosomes. Thus, it is during metaphase that the paired chromosomes precisely line up between the centrioles, ready for separation.
