Mitosis and nuclear division mechanisms constitute the fundamental biological processes ensuring the faithful segregation of replicated chromosomes into two genetically identical daughter nuclei within eukaryotic cells. This concept formalizes the sequential stages of nuclear division—prophase, metaphase, anaphase, and telophase—driven by the regulated assembly of the mitotic spindle and the controlled condensation and decondensation of chromatin. As a core mechanism of the cell cycle, it serves as the primary theoretical framework for understanding asexual reproduction, tissue growth, and maintenance of genomic stability across diverse eukaryotic organisms.
