What occurs during mitosis?

During mitosis, the primary event is the division of the nucleus, which results in the formation of two genetically identical daughter cells. This process is essential for growth, maintenance, and repair of tissues in multicellular organisms. During the various phases of mitosis—prophase, metaphase, anaphase, and telophase—chromosomes are duplicated and evenly divided between the two daughter cells, ensuring that each cell receives an exact copy of the parent cell's genetic material. This characteristic of mitosis is what distinguishes it from other processes, such as meiosis, where genetic diversity is a key feature. Therefore, understanding that the outcome of mitosis is two identical daughter cells stemming from a single nucleus division highlights the role of mitosis in maintaining genetic consistency across cell generations.
