Changes that occur in a cell during telophase:
- The polar fibers continue to lengthen.- Nuclei (plural form of nucleus) begin to form at opposite poles.
- The nuclear envelopes of these nuclei are formed from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.
- Nucleoli (plural form of nucleolus) also reappear.
- Chromatin fibers of chromosomes uncoil.
- After these changes, telophase/mitosis is largely complete and the genetic "contents" of one cell have been divided equally into two.
