If a cell has 40 chromosomes how many centromeres would it have when it is in metaphase?

=after any cell does mitosis it's 2 daughter cells will have the same amount of chromosomes as the parent cell meiosis is different then mitosis=

Chromosomes centromeres are attached to the kinetochere fibers?
It happen only during late-metaphase and anaphase of nuclear division. The kinetochore fibers after attaching with centromeres of all the chromosomes help in the separation of daughter chromosomes and facilitate further movement of these chromosomes on the opposite side.
Which step of mitosis are the chromosomes lined up in the center of the cell?
Metaphase is the stage where the chromosomes are align in the center of the cell.
Chromosomes align in center of cell?
prohase
Metaphase?
Chromosomes are in the middle of the cell.
What stage of meiosis is when chromosomes line up in the center of the cell?
Chromosomes line up in the middle of the cell during meiosis.
What phase do chromosomes line up?
During metaphase.A trick is to remember: "M for metaphase, M for the middle of the cell". This is to remind you that at metaphase the centromeres of the chromosomes are aligned in the plane of the equator.
To which part of the centromere do mitotic spindle fibers attach during prometaphase?
The centromeres of chromosomes attach to the spindle fibers during metaphase. The spindle fibers bring about the separation of sister chromosomes to the opposite poles. When spindle fibers do not attach to the centromeres, the doubling of chromosomes leads to polyploidy in the cell.
Where are chromosomes located during metaphase?
During metaphase, the chromosomes begin their line up along the metaphase plate, or an imaginary plate located at the midpoint between the two poles of the cell where the centrosomes are located. The chromosomes are placed their by the spindle fiber that are microtubules protruding from the centrosomes and attach to the centromeres.
When do chromosomes line up at the equator of a cell?
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 happen during metaphase stage of mitosis?
In metaphase, the chromosomes line up in the center of the cell (aka the metaphase plate or equatorial plate) and then the spindle fibers attach to the centromeres. Centromeres: the center of the two conjoined chromosome pairs where they will break into two halves in the next phase Picture of metaphase on Wikipedia: http://upload.wikimedia.org/wikipedia/commons/thumb/0/07/Metaphase.svg/800px-Metaphase.svg.png
What is created in metaphase?
metaphase is the phase of mitosis in which the chromosomes line up across the center of the cell and the centromeres attach to the spindle fibers. Good luck!! I learned this in 7th grade science this year. Tricky stuff!!!
Chromosomes centromeres are attached to the kinetochere fibers?
It happen only during late-metaphase and anaphase of nuclear division. The kinetochore fibers after attaching with centromeres of all the chromosomes help in the separation of daughter chromosomes and facilitate further movement of these chromosomes on the opposite side.
Which phase of mitosis is where the chromosomes are located at the equator of the cell?
Metaphase is the third phase of mitosis, when the chromosomes line up at the equator of the cell.
Which step of mitosis are the chromosomes lined up in the center of the cell?
Metaphase is the stage where the chromosomes are align in the center of the cell.
Chromosomes align in center of cell?
prohase
What is the phase when the chromosomes line up across the middle of the cell?
Chromosomes line up across the center of the cell is the Anaphase :D
What is the function of the spindle?
Spindle fibers attach to the centromeres at metaphase and separate the splited chromosomes from each other.Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.
