![]() The phosphorylation of the protein targets of M-Cdks (Mitotic Cyclin-dependent Kinases) drives spindle assembly, chromosome condensation and nuclear envelope breakdown in early mitosis. Telophase is primarily driven by the dephosphorylation of mitotic cyclin-dependent kinase (Cdk) substrates. Telophase accounts for approximately 2% of the cell cycle's duration.Ĭytokinesis typically begins before late telophase and, when complete, segregates the two daughter nuclei between a pair of separate daughter cells. ![]() ![]() The mitotic spindle is disassembled and remaining spindle microtubules are depolymerized. As chromosomes reach the cell poles, a nuclear envelope is re-assembled around each set of chromatids, the nucleoli reappear, and chromosomes begin to decondense back into the expanded chromatin that is present during interphase. During telophase, the effects of prophase and prometaphase (the nucleolus and nuclear membrane disintegrating) are reversed. Telophase (from Ancient Greek τέλος ( télos) 'end, result, completion', and φάσις (phásis) 'appearance') is the final stage in both meiosis and mitosis in a eukaryotic cell.
