At the center! Sister chromatids are identical copies of a given chromosome. before the cell divides it must first copy the entire genome. sister chromatids are shaped like > and < and are linked at the centromere. The tips are called telomeres.

What significant event happens in metaphase of mitosis?
The chromosome pairs are lined up in the center of the cell, parts of the cytoskeleton have formed the mitotic spindle and are preparing to pull the pairs apart.
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.
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
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!
During which stage of mitosis do the chromosomes line up along the equuator of the cell?
Metaphase.
What chromosomes align single file along the equator of a haploid cell?
during the metaphase. and they are called sister chromatids, not double chromosomes
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.
How do chromosomes move inside a cell during cell division?
During metaphase they line up along the cell's equatorial plane as pairs of sister chromatids, and during anaphase the sister chromatids separate (now called chromosomes) and are pulled to opposite poles of the cell.
What phase of mitosis do sister chromatids line up in the center of the cell?
This phase is called the metaphase. Remember' M' for middle and 'M' for metaphase. In the next phase (anaphase) the chromosomes move away from each other: remember 'A' for away. Telophase is the last or 'terminal' phase: remember 'T' for terminal. Prophase occurs prior to (ie before) the other phases: remember 'P' for prior. Interphase is in between cells divisions: remember 'I' for in between. Clear answer is metaphase.

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.
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.
How many chromosomes are present during prophase metaphase and telophase?
In prophase, there are 46 condensed chromosome pairs. The chromosomes replicated during S phase (Doubling the original 23 pairs) and now appear as two sister chromatids connected via the centromere. During metaphase, the kinetochores of the chromatids attach to the spindle fibers and the chromosomes have now moved into position along the metaphase plate (an imaginary division) and are roughly central in the cell. During anaphase the spindles begin pulling the chromatids apart from one another and telophase begins. During telophase, the nuclear envelopes of the cells to be forms. At this point it's a tad murky as the chromosomes are clearly separated but the cell has not yet made a complete divide. The division completes during cytokinesis beginning with the formation of a cleavage furrow will separate the cytoplasm and eventually yields two daughter cells. At this point the cell will have 23 chromosome pairs. The above is only true if we are talking about a somatic cell. If we are talking about a sex cell i.e a sperm or an egg then after the first meiotic division, there will be another one that follows the same processes as the first, only this time without the luxury of having undergone the replication during S phase and as such once cytokinesis finishes there will only be 23 single chromosomes in the given sex cell.
What two things happen during Metaphase?
During metaphase - the second stage of mitosis in the eukaryotic cell cycle - the chromosomes, pulled by the spindle fibers, line up along the middle of the cell, halfway between the centrosomes in the middle of the dividing cell. The chromosomes are now maximally condensed. In mitosis, individual replicated chromosomes, each composed of two sister chromatids, move to the equatorial plate during this step (whereas during the first division of meiosis, pairs of replicated chromosomes (tetrads) line up at this stage). This lack of pairing between homologs during mitosis is a fundamental distinction between mitosis and meiosis. Mitosis, unlike meiosis, produces identical daughter cells, because each homolog divides into two identical chromatids during anaphase.
Describes what happens during metaphase?
Chromosomes align along equator, or metaphase pate of cell.
During which stage of meiosis are the bivalents arranged along the equator?
During the metaphase I meiosis are the bivalents are arranged along the equator. During the prophase I of meiosis I the crossing over occurs.
The plane at the equator of the cell along which the chromosomes line up during metaphase is called?
Metaphase plate
