In anaphase, centromeres break and chromosomes begin migration toward opposite poles of the cell.
During anaphase, the centromeres divide, and the sister chromatids are pulled apart and move towards opposite poles of the cell. This is when the chromosomes separate and ensure that each new daughter cell receives a complete set of chromosomes.
In anaphase 1 of meiosis, the centromeres divide, separating the pairs of homologous chromosomes. Each chromosome is then pulled toward opposite poles of the cell by the spindle fibers attached to the centromeres. This results in the distribution of one member of each homologous pair to each daughter cell.
The chromatids break apart at the centromere during the anaphase of mitosis. This is when the spindle fibers pull the individual chromosomes toward opposite poles of the cell.
During metaphase, chromosomes are being directed to the cell's equatorial plane, and during anaphase, chromosomes are being directed to opposite poles of the cell.
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.
The centromeres of each chromosome finally separate, and the sister chromatids come apart. The sister chromatids of each chromosome now move as two individual chromosomes toward opposite poles.
Spindle microtubules attach to the centromeres, facilitating their alignment and separation during cell division. The microtubules help pull the duplicated chromosomes apart by exerting force on the centromeres, ensuring that each daughter cell receives the correct number of chromosomes. This process ensures equal distribution of genetic material during cell division.
During the anaphase stage of mitosis, centromeres divide and the sister chromatids are separated as they are pulled towards opposite poles of the cell by the spindle fibers. This results in the chromosomes moving toward their respective poles.

Mitosis consists of four main phases: Prophase: Chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form. Metaphase: Chromosomes align at the cell's equatorial plane, and spindle fibers attach to the centromeres of the chromosomes. Anaphase: Sister chromatids are pulled apart toward opposite poles of the cell as the spindle fibers shorten. Telophase: Chromatids reach the poles, the nuclear envelope re-forms around each set of chromosomes, and the chromosomes begin to de-condense back into chromatin.
Spindle fibers are crucial for the proper distribution of chromosomes during cell division. They form a structure called the mitotic spindle that attaches to the chromosomes at their centromeres through protein complexes known as kinetochores. As the spindle fibers contract and shorten, they pull the sister chromatids apart toward opposite poles of the cell, ensuring that each daughter cell receives an identical set of chromosomes. This precise mechanism is essential for maintaining genetic stability in the resulting cells.
The chromatids break apart at the centromere during the anaphase of mitosis. This is when the spindle fibers pull the individual chromosomes toward opposite poles of the cell.
Kinetochores move toward the poles during anaphase of mitosis. This movement is driven by the depolymerization of microtubules attached to the kinetochores, pulling the chromosomes to opposite ends of the cell.

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.
During metaphase, chromosomes are being directed to the cell's equatorial plane, and during anaphase, chromosomes are being directed to opposite poles of the cell.
