Sagot :
Metaphase is when the chromosomes attach to the spindle fibers by their centromeres
This can be confused with the phases:prophase where the spindle fibers form a bridge between the ends of the cell, and anaphase where the spindle fibers draw the chromosomes to the opposite ends of the cell(the cell splits up)
This can be confused with the phases:prophase where the spindle fibers form a bridge between the ends of the cell, and anaphase where the spindle fibers draw the chromosomes to the opposite ends of the cell(the cell splits up)
In the metaphase, chromosomes attach to the spindle fibers by their centromeres.
Further Explanation:
Mitosis is an equational division phase of the reproductive cell cycle in which spindles binds to the chromosome and move the sister chromatid separate. It is an essential step for the separation of genetic material. In the cytokinesis phase, the cytoplasm separates and forms two daughter cells. It consists of four steps:
• Prophase
• Metaphase
• Anaphase
• Telophase
In metaphase, the chromosomes are aligned in the center of the cell that indicates the second stage of mitosis. The cohesion protein plays a key role in the chromosome segregation process. It mediates cohesion between replicated sister chromatids. It is the phase where chromosomes attach to the spindle fibers by their centromeres. The cohesion protein that holds the sister chromatids together at the centromere is removed in anaphase. In this phase, the genetic material is present in the condensed form known as chromosomes.
