what happens to chromosomes during anaphase
chromosomes and the mitotic spindles are formed during anaphase
During mitosis, in the stage of telophase daughter chromosomes arrive at the poles. Daughter chromosomes begin their travel to the end poles in the stage of anaphase.
They are separated in Anaphase I of Meiosis I.
Anaphase I, and then again in Anaphase II--two seperations occur in meiosis.
Chromosomes split into two poles during the anaphase stage of mitosis. This separation ensures that each daughter cell receives the correct number of chromosomes.
Centromeres divide and sister chromosomes become full-fledged chromosomes during the anaphase stage of mitosis. This is when the sister chromatids are pulled apart towards opposite poles of the cell, ultimately becoming individual chromosomes.
In the context of cell division, chromosomes will aline in the middle of the cell during metaphase, then during anaphase they are pulled apart into two daughter cells by centrioles. I wouldn't say they are ever on opposite poles, also considering that there is no directionality of a cell.
The sister chromatid separate during anaphase II in meiosis. During anaphase I homologous chromosomes get separated.
The chromatids become daughter chromosomes during the anaphase stage of meiosis, specifically during anaphase II in the case of meiosis II. In these stages, the chromatids are separated and move towards opposite poles of the cell, becoming individual chromosomes.
Homologous chromosomes segregate towards opposite poles of a dividing cell during the anaphase stage of mitosis.
