what happens to chromosomes during anaphase
In Anaphase I
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
A chromosome holds genetic information for the organism.
During anaphase, the sister chromatids of each chromosome are pulled apart by the spindle fibers. The chromatids, now individual chromosomes, move toward opposite poles of the cell. This separation ensures that each daughter cell will receive an identical set of chromosomes. Anaphase is a critical stage in both mitosis and meiosis, facilitating proper chromosome distribution.
In anaphase of mitosis, the chromosomes are duplicated and each pair is separated. For a chimpanzee with a diploid chromosome number of 48, there are 24 pairs of chromosomes. During anaphase, each chromosome is split into two sister chromatids, resulting in 48 monads (individual chromatids) in a somatic cell.
The tetrads are pulled apart.
The moving part of each homologous chromosome during anaphase I of meiosis is called a chromatid. Each chromatid is a single strand of DNA that is duplicated during the S phase of the cell cycle and remains joined to its sister chromatid at the centromere until they separate during anaphase.
The chromosomes are dividing and becoming new chromosomes.

It depends on whether you're talking about mitosis or meiosis. In mitosis, it is during anaphase. In meiosis, where the cell divides twice, centromeres aren't separated until anaphase II. In anaphase I, chromosomes are arranged as tetrads, and these tetrads are pulled apart to create two daughter cells, each with a full copy of the original cells' diploid chromosome.
This occurs during anaphase.
