How do microtubules shorten during anaphase
WebDuring anaphase, the sister chromatids are separated and pulled towards opposite poles of the cell by the shortening of the chromosomal microtubules. The overlap microtubules do not shorten, but instead lengthen to push the two poles of the cell apart. The movement of daughter chromosomes towards opposite poles is also a characteristic event of ... Websister chromatids are pulled apart during the anaphase of cell division; Sister Chromatids.
