During what stage the centromere does not divide?
The centromere does not divide during the anaphase of meiosis I. In this stage, homologous chromosomes separate and move to opposite poles, but the sister chromatids remain attached at their centromeres. Division of the centromere occurs later, during anaphase II of meiosis when the sister chromatids finally separate.
Do the individual chromosomes move apart in mitosis or meiosis?
Yes, in both mitosis and meiosis, the individual chromosomes move apart during cell division. In mitosis, the sister chromatids of each chromosome separate and move to opposite poles of the cell, while in meiosis, homologous chromosomes separate in the first division and sister chromatids separate in the second division.
Which specific structure must separate during anaphase in order for sister chromatids to begin moving toward opposite poles?
During anaphase, the centromere must separate for sister chromatids to start moving towards opposite poles. This separation allows each chromatid to be pulled to the poles by the spindle fibers attached to the centromere.
What separates during meiosis 2?
In Meiosis, Anaphase 2 sister chromatids (individual strands) separate and one of each duplicate goes to each side of the cell.
Which stage of meiosis do chromatids separate and become daughter chromosomes?
Chromatids separate and become daughter chromosomes during anaphase II of meiosis. In this stage, the sister chromatids, which were previously aligned at the metaphase plate, are pulled apart by spindle fibers and move toward opposite poles of the cell. This separation reduces the chromosome number in the daughter cells, leading to the formation of gametes. Following this, the cells will undergo cytokinesis to complete the process.

What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What is the difference between anaphase1 and anaphase2?
Anaphase 1 is the phase in meiosis where homologous chromosomes separate and move to opposite poles of the cell. Anaphase 2, on the other hand, is the phase in meiosis where sister chromatids separate and move to opposite poles of the cell. Essentially, anaphase 1 involves the separation of homologous chromosomes, while anaphase 2 involves the separation of sister chromatids.
Which specific structure must separate during anaphase in order for sister chromatids to begin moving toward opposite poles?
During anaphase, the centromere must separate for sister chromatids to start moving towards opposite poles. This separation allows each chromatid to be pulled to the poles by the spindle fibers attached to the centromere.
Name the stage of meiosis during which chromatids are separated to opposite poles of the cell?
Anaphase II is the stage of meiosis in which chromatids are separated to opposite poles of the cell. This leads to the formation of haploid daughter cells with distinct chromosomes.
During anaphase of meiosis do the chromosomes have one or two chromatids as they move toward the poles?
During the anaphase stage of mitosis the two chromatids become separate chromosomes. The chromatids are pulled apart and move toward their centrosomes. As they move toward the poles, the centrosomes go first, followed by the chromatids, forming a â??vâ?? shape.
What separates during meiosis 2?
In Meiosis, Anaphase 2 sister chromatids (individual strands) separate and one of each duplicate goes to each side of the cell.

This separation reduces the chromosome number in the daughter cells, leading to the formation of gametes. Following this, the cells will undergo cytokinesis to complete the process.
When do cohesins break down?
Cohesins break down during the metaphase-anaphase transition of mitosis or meiosis. This breakdown allows sister chromatids to separate and move towards opposite poles of the cell.
What happens to sister chromatids in meiosis?
They are separated and pulled to the opposite ends, or poles.
Cohesion break down in which stage of mitosis?
Cohesion breakdown occurs in the anaphase stage of mitosis, where the protein complexes that hold sister chromatids together are cleaved, allowing the chromatids to separate and move towards opposite poles of the cell.
