Anaphase is a term that is commonly used in biology to describe the third stage of mitosis. During this stage, the chromosomes begin to separate and move towards opposite ends of the cell. Although anaphase is a specific term that refers to this particular stage of cell division, there are several synonyms that can be used to describe it. These include words such as separation phase, splitting phase, and chromosomal segregation phase. Additionally, some researchers may also use more technical terms such as metaphase-anaphase transition or anaphase onset to describe this important stage in the cell cycle.
