What is it called when the nuclear membranes begin to form around each group of chromosomes during mitosis?

The process when nuclear membranes begin to form around each group of chromosomes during mitosis is called telophase. During this stage, the separated sister chromatids reach opposite poles of the cell, and the nuclear envelope reassembles around each set of chromosomes, leading to the formation of two distinct nuclei. This marks the near end of mitosis, followed by cytokinesis, where the cytoplasm divides, resulting in two daughter cells.
