During anaphase where do microtubules shorten
WebTwo separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles.... WebAnaphase is the stage of mitosis in which the replicated chromosomes are separated and moved towards opposite poles of the cell. The movement of chromosomes during anaphase is essential for successful cell division, and it is mediated by a number of cellular processes, including the elongation and shortening of microtubules.
