They are called poles, for example in anaphase chromosomes are pulled to the opposite poles of the cell.
The opposite ends of a cell are called the poles. These poles play a key role in cell division and directionality of cellular processes.
During anaphase of cell division, centromeres break apart and chromosomes begin their migration towards opposite poles of the cell. This is a crucial stage where sister chromatids separate and are pulled towards the poles by the mitotic spindle fibers.
Chromosomes move to opposite poles of the cell.
This event occurs in prophase.
Homologous chromosomes segregate towards opposite poles of a dividing cell during the anaphase stage of mitosis.
Spindle Fibers
Chromosomes reach the opposite sides of the cell during anaphase of mitosis or meiosis. In this phase, the sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell. This separation ensures that each daughter cell will receive an identical set of chromosomes. Once they have reached the poles, the cell can proceed to the next stage, which is telophase.
