Metaphase is a stage in cell division, specifically in mitosis, when the chromosomes align at the equator of the cell. It is preceded by prophase and prometaphase, and followed by anaphase.
During metaphase, the replicated chromosomes, which have already undergone DNA replication during interphase, line up along the middle of the cell. This alignment is facilitated by the spindle fibers, which extend from opposite ends of the cell and attach to the centromeres of each chromosome. These spindle fibers help to position the chromosomes in a precise and orderly manner.
Metaphase ensures that the chromosomes are properly aligned before they are separated and distributed to two daughter cells during anaphase. This alignment is crucial for the successful division of genetic material in the cell.
Metaphase is easily recognizable under a microscope, as the chromosomes appear as a neat and organized line in the center of the cell. This visual arrangement is often used to study and analyze the chromosomes, especially in genetic research and diagnostics.
