Final answer:
During mitosis, the replicated genetic material is divided into two new nuclei through a series of five phases: prophase, prometaphase, metaphase, anaphase, and telophase, followed by cytokinesis to form two identical daughter cells.
Step-by-step explanation:
During the five phases of mitosis, the replicated genetic material is partitioned into two new nuclei. The process begins with prophase, where chromosomes condense and the nucleolus disappears.
This is followed by prometaphase where the nuclear envelope breaks down and microtubules attach to chromosomes. Next comes metaphase, where chromosomes align at the equatorial plate.
Anaphase is the third stage where sister chromatids separate and move to opposite poles of the cell, leading to two new nuclear regions.
Finally, telophase sees the arrival of chromosomes at the poles, their decondensation, and the re-formation of the nuclear envelopes. After telophase, cytokinesis splits the cytoplasm into two separate cells, each having a complete and fully functional nucleus.
