(⑤)Telophase Reorganization of nuclei:Dephosphorylation of histone, chromosome decondensation,nucleolus appears,rRNA begin to synthesize,assembly of nuclear envelope. Degradation of spindle,formation of contractile ring, cytoplasm divide. Telophase The separating chromosomes reach the poles. Telophase passes into the next interphase as the nuclear envelopes and nucleoli re-form and the chromatin becomes diffuse 16 This document is produced by trial version of Print2Flash.Visit www.print2flash.com for more informatior

(6)Cytokinesis Cytokinesis is the last stage of mitosis, giving rise to two daughter cells. Cytokinesis usually initiates in late anaphase and is triggered by the inactivation of MPF, thereby coordinating nuclear and cytoplasmic division of the cell. 18 This document is produced by trial version of Print2Flash.Visit www.print2flash.com for more information
Cytokinesis of animal cells is mediated by a contractile ring of actin and myosin Il filaments that forms beneath the plasma membrane. The location of this ring is determined by the position of the mitotic spindle. Cleavage proceeds as contraction of the actin-myosin filaments pulls the plasma membrane inward,eventually pinching the cell in half.
