What phase does chromatids line up along the equater?
Metaphase II In Metaphase I, the tetrads of homologous chromosomes line up along the equator, but they are not individual chromosomes.
What chromosomes align single file along the equator of a haploid cell?
during the metaphase. and they are called sister chromatids, not double chromosomes
How many chromosomes are in metaphase?
Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
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.
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.
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.
How do metaphase of meiosis I and meiosis II differ?
It is different because pairs of chromosomes line up down the middle and in metaphase II single chromosomes are lined up across the middle
How does the alignment of chromosomes differ at the equator between metaphase of mitosis and metaphase of meiosis 1?
In prophase the membrane of nucleus disappears, then the nucleus too, chromosomes unwrap, collocation of spindle apparatus is completed. In metaphase: chromosomes line up on equatorial cell-plate. there is very little difference
When the chromosomes line up in mitosis this is known as what stage?
Metaphase II
What is the activity of chromosomes in metaphase 1 of meiosis?
In Mitosis during Metaphase, the chromosomes line up on the metaphase plate, but without their homologues. In Meiosis during Metaphase I, the tetrads line up on the metaphase plate. Then it's back to double-stranded chromosomes lining up in Metaphase II. I
Stage when chromosomes align in one plane?
Mitosis is the process of cell division which involves 5 different phases. These phases include prophase, prometaphase, metaphase, anaphase and telophase. Metaphase is the phase in which the chromosomes line up in the middle of the cell.
What phase of mitosis does the cell contain four chromosomes?
its Anaphase IIAnaphase
