teleófázis

Teleófase is the final stage of mitosis and meiosis, the processes of cell division. In mitosis, telophase follows anaphase. During telophase, the chromosomes that were separated in anaphase arrive at opposite poles of the cell. The chromosomes begin to decondense, meaning they uncoil and become less tightly packed. Simultaneously, nuclear envelopes reform around each set of chromosomes at the poles, creating two distinct nuclei within the single cell. The spindle fibers that were responsible for separating the chromosomes also disassemble. Cytokinesis, the division of the cytoplasm, typically overlaps with telophase and results in the formation of two separate daughter cells.

In meiosis, telophase occurs twice. In meiosis I, telophase I follows anaphase I, and similar to mitosis, chromosomes arrive at opposite poles, nuclear envelopes reform, and cytokinesis may occur, resulting in two haploid cells. Meiosis II follows meiosis I, and telophase II takes place after anaphase II. In telophase II, the sister chromatids that have been separated arrive at opposite poles, decondense, and new nuclear envelopes form around them. Cytokinesis then completes the process, yielding a total of four genetically distinct haploid daughter cells. Teleófase is crucial for ensuring that each daughter cell receives a complete and correct set of genetic material.
