The cell division process that shortens to pull the chromatids apart is called anaphase, which is a stage of mitosis and meiosis. During anaphase, the spindle fibers attached to the centromeres of the chromatids shorten, pulling the sister chromatids toward opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes.
spindle fibers
The fibers that shorten and pull the chromatids apart are called microtubules. During cell division, microtubules form the spindle apparatus and attach to the chromosomes to facilitate their separation.
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.
Chromosomes in the cell are pulled apart by spindle microtubules during cell division to ensure that each new cell receives the correct number of chromosomes.
During anaphase, the cell begins to elongate as the sister chromatids are pulled apart toward opposite poles of the cell. The spindle fibers attached to the chromatids shorten, while those not attached to chromosomes lengthen, pushing the poles further apart. This elongation is crucial for preparing the cell for division.

Chromosomes in the cell are pulled apart by spindle microtubules during cell division to ensure that each new cell receives the correct number of chromosomes.
During cell division, sister chromatids are joined at the centromere by protein complexes called cohesins. These cohesins hold the sister chromatids together until they are separated during the later stages of cell division.
During anaphase, the cell begins to elongate as the sister chromatids are pulled apart toward opposite poles of the cell. The spindle fibers attached to the chromatids shorten, while those not attached to chromosomes lengthen, pushing the poles further apart. This elongation is crucial for preparing the cell for division.
spindle apparatus
Chromatids are separated during cell division by a structure called the mitotic spindle, which attaches to the centromere of each sister chromatid. The spindle fibers then pull the sister chromatids apart towards opposite poles of the cell, ensuring that each daughter cell receives the correct number of chromosomes.
The number of sister chromatids in a human body cell entering cell division is twice the haploid number, as each chromosome is replicated and consists of two sister chromatids held together by a centromere. This means that there are 46 pairs of sister chromatids in a normal human body cell entering cell division.
During anaphase, the sister chromatids (duplicated copies of a chromosome) are pulled apart and move to opposite poles of the cell by the spindle fibers, which are composed of microtubules. This process ensures that each daughter cell receives an identical set of chromosomes during cell division.
Centromeres split during cell division in the mitotic phase called anaphase. As the sister chromatids are pulled apart towards opposite poles of the cell, the centromeres divide, forming individual chromatids that will become separate chromosomes in the daughter cells.
