=== Movement of centrosomes === During prophase in [[Cell (biology)|animal cells]], [[centrosome]]s move far enough apart to be resolved using a [[light microscope]].<ref name=":2" /> [[Microtubule]] activity in each [[centrosome]] is increased due to recruitment of [[Tubulin#Ξ³-Tubulin|Ξ³-tubulin]]. Replicated [[centrosome]]s from [[interphase]] move apart towards opposite poles of the cell, powered by [[Motor protein|centrosome associated motor proteins]].<ref name=":4">{{Cite book|title=Essential Cell Biology| vauthors = Alberts B, Bray D, Hopkin K, Johnson A, Lewis J, Raff M, Roberts K, Walter P |publisher=Garland Science|year=2004|isbn=978-0-8153-3481-1|location=New York NY|pages=[https://archive.org/details/essentialcellbio00albe/page/639 639β658]|url=https://archive.org/details/essentialcellbio00albe/page/639}}</ref> Interdigitated interpolar [[microtubule]]s from each [[centrosome]] interact with each other, helping to move the [[centrosome]]s to opposite poles.<ref name=":4" /><ref name=":2" />
