Question: 1 / 400

In what phase of mitosis do chromosomes align at the cell's equatorial plane?

Prophase

Anaphase

Metaphase

During mitosis, chromosomes align at the cell's equatorial plane during the metaphase. This is a critical stage where the chromosomes, which have already been replicated and condensed, are arranged along the middle of the cell, known as the metaphase plate.

In this phase, spindle fibers attached to the kinetochores of the chromosomes ensure that each chromosome aligns precisely at the center of the cell. This alignment is essential for ensuring that when the chromosomes are pulled apart to opposite poles in the subsequent anaphase, each daughter cell receives an identical set of chromosomes.

This precise organization during metaphase is crucial for maintaining genetic stability in the daughter cells. If the chromosomes were not properly aligned, it could lead to unequal distribution of genetic material, which can result in conditions such as aneuploidy.
