Anaphase movement and its significance
The chromosomal movement towards the pole mediated by spindle that separate sister chromatids is referred to as anaphase movement. It comprises poleward movement of chromatids accompanied by the shortening of the kinetochore microtubules at anaphase A which is followed by anaphase B. The separation of poles themselves accompanied by elongation of polar microtubules.
The successful anaphase movement accomplishes the quantitatively equal distribution and qualitative distribution of chromosomes though the latter needs a exact replication in the proceeding S phase.
