Detailed explanation-1: -Telophase is also marked by the dissolution of the kinetochore microtubules and the continued elongation of the polar microtubules. As the nuclear envelopes re-form, the chromosomes begin to decondense and become more diffuse.
Detailed explanation-2: -During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
Detailed explanation-3: -Some cellular proteins act to disassemble microtubules, either by severing microtubules or by increasing the rate of tubulin depolymerization from microtubule ends. Other proteins (called microtubule-associated proteins or MAPs) bind to microtubules and increase their stability.
Detailed explanation-4: -During prophase, when levels of mitotic kinase activity rise, interphase microtubules were gradually disassembled, in part as a result of phosphorylation-induced inactivation of the microtubule stabiliser Ensconsin/MAP7.
