During what the sister chromatids line up in the midplane of the cell?
During metaphase in mitosis, sister chromatids line up in the midplane of the cell before they are separated and pulled towards opposite poles.
What do you call the imaginary line that chromosomes line up at during meta phase?
The imaginary line that chromosomes line up at during metaphase of cell division is called the metaphase plate. This is where the sister chromatids align before being separated during anaphase.
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's the difference between meiosis ii and mitosis?
In both cases chromosomes line up and sister chromatids are separated by the action of the spindle fibers. The daughter cells are genetically identical to one another
In what way meiosis 2 similar to mitosis?
Meiosis II is similar to mitosis in that both processes involve the separation of sister chromatids. In meiosis II, the sister chromatids that were formed during meiosis I are separated into individual chromosomes, similar to how sister chromatids are separated in mitosis. This results in the formation of haploid daughter cells in both meiosis II and mitosis.
During which phase of mitosis do the sister chromatids line up in the center of the cell?
Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
During what the sister chromatids line up in the midplane of the cell?
During metaphase in mitosis, sister chromatids line up in the midplane of the cell before they are separated and pulled towards opposite poles.
During what phase does the sister chromatids line up in the midplane of the cell?
During Mitosis, the spindle pulls apart the sister chromatids of the chromosome in the Anaphase stage.
What is the difference between sister and non sister chromatids?
Sister chromatids are two identical copies of a single chromosome that are joined together by a centromere and are produced during DNA replication. Non-sister chromatids are chromatids belonging to different homologous chromosomes that can undergo genetic recombination during meiosis.
In mitosis chromatids line up in the middle of the cell?
Chromatids line up during the metaphase of the cell cycle.
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.
What happens in metaphase 2?
During metaphase of meiosis 2, or metaphase II, there are 3 major points. 1st is the chromosomes are positioned on the metaphase plate as in mitosis. 2nd is, because of the crossing over in meiosis I, the two sister chromatids of each chromosome are not genetically identical. 3rd is the kinetochores of sister chromatids are attached to microtubules extending from opposite poles.
How do chromosomes move inside a cell during cell division?
Chromosomes are moved by a complex cellular machinery called the mitotic spindle. This spindle is made up of microtubules that attach to the chromosomes and move them to opposite ends of the cell during cell division. The coordinated action of motor proteins helps ensure that each daughter cell receives the correct number of chromosomes.
Do the metaphase 2 line up in single or double file?
The metaphase 2 stage of meiosis line up in single file. Each chromosome aligns individually along the metaphase plate, ready for separation into two daughter cells during anaphase 2.
In mitosis's chromatids line up in the middle of the cell during?
In mitosis, chromatids line up in the middle of the cell during metaphase. This alignment ensures that, during anaphase, the chromatids can be separated and pulled to opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.
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.
How does the alignment of chromosomes differ at the equator between metaphase of mitosis and metaphase of meiosis 1?
In metaphase of mitosis, chromosomes align at the equator individually with sister chromatids facing opposite poles. In metaphase I of meiosis, homologous pairs of chromosomes line up at the equator with each pair consisting of one chromosome from the mother and one from the father, and crossing over may have occurred between homologous chromosomes.
