Final answer:
During telophase, the chromosomes relax and unwind, while the mitotic spindles are broken down into tubulin monomers. Nuclear envelopes form around the chromosomes.
Step-by-step explanation:
During telophase, the chromosomes reach the opposite poles and begin to decondense (unravel), relaxing into a chromatin configuration. The mitotic spindles are depolymerized into tubulin monomers that will be used to assemble cytoskeletal components for each daughter cell. Nuclear envelopes form around the chromosomes, and nucleosomes appear within the nuclear area.
During Telophase of mitosis, chromosomes decondense, the mitotic spindle disassembles into tubulin monomers, and new nuclear envelopes form around the chromosomes, leading to the creation of separate nuclei.
During the phase of Telophase in mitosis, several reverse processes occur. The chromosomes that have reached the opposite poles of the cell begin to decondense, transitioning back into a less condensed chromatin configuration. Simultaneously, the mitotic spindle is disassembled; the microtubules that composed it shorten and depolymerize into tubulin monomers, which will be reused to assemble new cytoskeletal components for the developing daughter cells. Additionally, new nuclear envelopes are formed around each set of chromosomes, leading to the establishment of separate nuclei, signaling the end of mitosis and preparing the way for cytokinesis, where the cell will complete its division into two independent daughter cells.
