Explanation:
Detailed explanation-1: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).
Detailed explanation-2: -The mitotic phase (M) includes both mitosis and cytokinesis. This is when the nucleus and then the cytoplasm divide.
Detailed explanation-3: -Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word “mitosis” means “threads, ‘’ and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
