What is the outcome of telophase?

In telophase, the key outcome is that the nuclear envelope reforms around each set of separated sister chromatids, resulting in the formation of two distinct nuclei within the cell. This marks the conclusion of nuclear division (mitosis or meiosis), effectively restoring the nuclear structure after the chromosomes have been segregated to opposite poles of the cell. By reestablishing the nuclear envelopes, telophase prepares the cell for the next phase of cell division, cytokinesis, where the cytoplasm will divide, leading to the formation of two separate daughter cells. This process is vital for ensuring that each daughter cell receives a complete set of genetic material.

The other options describe events or states that either happen before or after telophase, or do not accurately reflect the outcome of this specific phase in cell division. For instance, cytokinesis follows telophase, while the visibility of chromatids usually pertains to earlier phases of mitosis. The option regarding the loss of DNA is incorrect, as DNA is not lost during telophase but rather properly distributed between the daughter cells.
