Telophase is the final stage of cell division, specifically during mitosis or meiosis

Telophase is the final stage of cell division, specifically during mitosis or meiosis. It is preceded by anaphase and followed by cytokinesis. During telophase, the separated sister chromatids or homologous chromosomes reach opposite poles of the cell.

One of the key events in telophase is the reformation of a nuclear envelope around each set of chromosomes. The nuclear membrane disintegrated during prophase and is now reassembled. This reformation helps restore the two distinct nuclei in the newly formed daughter cells.

In addition to the nuclear envelope formation, telophase also involves the decondensation of the chromosomes. In the earlier stages of mitosis or meiosis, the chromosomes were condensed and tightly coiled for efficient separation. However, in telophase, this compact structure unravels and elongates, making it easier for the genetic material to be accessed and transcribed.

During telophase, the microtubules that were responsible for separating the chromosomes start to disassemble. This disassembly process is crucial for the completion of cell division. As the microtubules break down, the chromosomes gradually move towards opposite sides of the dividing cell.

Finally, cytokinesis occurs, usually concurrently with telophase, which completes the physical division of the cell into two distinct daughter cells. Although cytokinesis is often considered a separate stage, it overlaps with telophase and involves the formation of a cleavage furrow in animal cells or a cell plate in plant cells. These structures gradually pinch or grow inwards, separating the cytoplasm of the parent cell into two separate compartments, each containing its own nucleus and other organelles and structures.

In summary, telophase is the final stage of cell division, where the nuclear envelope reforms, chromosomes decondense, microtubules disassemble, and cytokinesis occurs. It marks the completion of the cell division process and the formation of two genetically identical daughter cells.
