Metaphase is the second stage of mitosis and each division of meiosis. During metaphase, chromosomes line up along the equator of the cell's spindle. Chromosome centromeres are attached to spindle microtubules using special proteins. Due to this, the chromosomes are located strictly in the middle of the cell.
In metaphase, condensation of chromosomes occurs - they shorten and thicken as much as possible so that they can be distinguished under a microscope. This is necessary so that each chromosome in the daughter cells receives its own identical copy.
Thus, the metaphase stage is critical for the precise distribution of genetic material between daughter cells. The genetic stability of dividing cells depends on the correct course of metaphase.
Metaphase is the second stage of cell division, during which alignment and attachment of chromosomes to the spindle occurs. This occurs as a result of the centromeres of the chromosomes connecting to the microtubules of the spindle. As a result of this process, the chromosomes are aligned along the equator of the cell and form a metaphase plate.
At metaphase, chromosomes can be observed to be arranged in two rows on either side of the cell's equator. In this case, the centromeres of the chromosomes are attached to microtubules, which are located on opposite sides of the cell.
During metaphase, the cell is in a state of maximum readiness for division. After the completion of metaphase, the next stage of division begins - anaphase.
