The identity of chromosomes as distinct elements is lost when they cluster at opposite spindle poles.
During telophase, spindle fibers break down.
To keep the nuclear DNA from the cytoplasm during telophase, a nuclear membrane and nucleoli develop around every pair of chromosomes.
The uncoiling and decondensing of the chromosomes cause them to become less compact and more diffuse.
The cytoplasm of the parental cell is split into two daughter cells during a process known as cytokinesis that occurs concurrently with telophase in the cell.
