Lastly, during telophase, a nuclear envelope forms around each set of chromosomes, and the chromosomes start to uncoil. Then, cytokinesis occurs (however, it is not a phase of mitosis). During cytokinesis, the cytoplasm divides, creating two new daughter cells. cumberland county real property search
