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.
What else can I help you with?
What stage of mitosis do the 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.
What are The phases of mitosis in which chromosomes line up at the equator is?
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.
Which phase of mitosis is where the chromosomes are located at the equator of the cell?
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.
How many chromatids will line up at the equator of the cell during mitosis?
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.
Which phase involves the chromosomes lining up along the equator of the cell?
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.
Where do the chromosomes line up along the cell?
chromosomes line up at the spindle equator during metaphase! chromosomes line up at the spindle equator during metaphase!
What is the name of the fibers that line the chromosomes up at the equator of the cell?
the answer is spindle!
What fibers line up the chromosomes at the equator of the cell?
Kinetochore Fibers
When does metaphase begin?
when chromosomes line up along the equator of the cell
What stage of mitosis do the 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.
What is the phase in cell division when the chromosomes line up at the cells equator?
Metaphase.
Which stage of a cells cycle do the replicated chromosomes line up on the equator of the cell?
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.
What is a sentence with metaphase in it?
At the stage of metaphase, chromosomes line up along the equator of the cell. Homologous chromosomes pair up.
What are The phases of mitosis in which chromosomes line up at the equator is?
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.
What stage of mitosis is occurring when the chromosomes start to align at the equator of the cell?
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.
What is another term for the center of the cell where the chromosomes line up during mitoses?
cell equator or equatorial plane
Chromatids line up along the equator?
The chromatids line up at the equator of the cell during the metaphase of meiosis. After which the chromatids separate to form individual chromosomes.
