Chromosomes line up with their centromeres on the equator during metaphase of any eukaryotic cell division: mitosis, meiosis I, or meiosis II.
During metaphase the arms of the chromosomes are spread out, but it will be the centromeres that lead the way towards the poles during anaphase. This is because in metaphase some spindle fibers, which are formed by the cytoskeleton, attach to the centromeres. It is the contraction of these fibers that pulls the chromosomes (daughter-chromosomes in mitosis and meiosis II) towards the poles in anaphase.
There is an important checkpoint during metaphase. If the spindle fibers are not correctly attached, division should stop. However, a few mistakes slip through the net, and sometimes both daughter-chromosomes of a pair (in other words, a pair of former sister-chromatids) move to the same pole. This phenomenon is called non-disjunction, and leads to an abnormal number of chromosomes in both daughter-nuclei.
The stage of mitosis where chromosomes line up along the equator of the cell is called metaphase. This is when the chromosomes are maximally condensed and attach to the spindle fibers at the centromere.
The phase of mitosis in which chromosomes line up at the equator is called metaphase. This is when the chromosomes align in the center of the cell, ready to be separated into daughter cells during anaphase.
The phase of mitosis where the chromosomes are located at the equator of the cell is called the metaphase. Here, the chromosomes align in the middle of the cell, ready to be separated during anaphase.
During mitosis, two sister chromatids from each chromosome will line up at the equator of the cell. This occurs after the chromosomes have replicated during the S phase of the cell cycle.
Metaphase 1 is the phase of mitosis when the chromosomes line up along the equator. Homologous chromosomes line up in the middle of the cell, then spindle fibers attach onto the homologous chromosome.

when chromosomes line up along the equator of the cell
The stage of mitosis where chromosomes line up along the equator of the cell is called metaphase. This is when the chromosomes are maximally condensed and attach to the spindle fibers at the centromere.
Metaphase.
The replicated chromosomes line up on the equator of the cell during metaphase of mitosis. This is when the spindle fibers attach to the centromeres of the chromosomes and align them at the center of the cell before they separate during anaphase.
At the stage of metaphase, chromosomes line up along the equator of the cell. Homologous chromosomes pair up.
The phase of mitosis in which chromosomes line up at the equator is called metaphase. This is when the chromosomes align in the center of the cell, ready to be separated into daughter cells during anaphase.
The stage of mitosis where chromosomes start to align at the equator of the cell is called metaphase. During metaphase, the chromosomes line up along the metaphase plate, ensuring that they will be equally divided between the two daughter cells during cell division.
