Mitosis is a fundamental process of cell division, where a single eukaryotic cell divides into two identical daughter cells. It is a complex and highly regulated series of events that ensures the faithful duplication and segregation of genetic material to the resulting progeny. During mitosis, the chromosomes condense and become visible under the microscope. They align at the metaphase plate, where the spindle fibers attach to the centromeres. The sister chromatids then separate and move towards opposite poles of the cell during anaphase, followed by the completion of cytokinesis, which divides the cytoplasm into two distinct cells. Mitosis plays a crucial role in growth, development, and tissue repair in multicellular organisms. It is also essential for maintaining genome stability, preventing mutations, and ensuring the proper functioning of cells. In the context of cellular biology and cell division, mitosis represents one of the two primary mechanisms of cell duplication, with the other being meiosis. While meiosis is specific to the production of gametes (sex cells) in sexual reproduction, mitosis occurs in both somatic and germline cells during asexual reproduction or tissue regeneration. Mitosis can be further divided into several substages, including prophase, prometaphase, metaphase, anaphase, and telophase. Each of these stages involves specific molecular events that contribute to the faithful replication and partitioning of genetic material. Overall, mitosis is a highly regulated process that ensures the accurate transmission of genetic information from one generation to the next.
