    each pole.” [2] In Telophase the chromosomes has reached poles and the microtubules disappear. Nuclear envelopes also become evident around chromosomes and the cell begins to divide. A process called Cytokinesis splits the cells cytoplasm where an actin contractile ring tightens the middle region of the cell. This then develops two separate yet identical daughter cells‚ “the spindle fibres disintegrate‚ nuclear envelops are formed around the chromosomes in each cell and the chromatin returns to its
