A.chromosomes aligning themselves at the equator.
<h3>What distinguishing features of mitosis' metaphase?</h3>
A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.
<h3>What distinguishes metaphase from other phases?</h3>
Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.
