Question: 1 / 400

Which phase of mitosis involves the alignment of chromosomes at the cell's equator?

Prophase

Metaphase

The phase of mitosis where chromosomes align at the cell's equator is known as metaphase. During metaphase, the chromosomes, which have already been duplicated and condensed, are lined up along the metaphase plate, an imaginary line that bisects the cell. This alignment is crucial for ensuring that each daughter cell receives an identical set of chromosomes, as the spindle fibers attached to the chromosomes will help pull them apart to opposite sides of the cell in the next phase, anaphase.

This precise alignment at the equator is a key feature of metaphase, as it ensures the proper separation and distribution of genetic material. Without this alignment, there could be errors during cell division that lead to genetic imbalances in the daughter cells.
