Mitosis is indeed the process referred to when talking about the division of a cell’s nucleus. It is one of the key stages in the cell cycle, specifically preceding cytokinesis, where the actual division of the cell’s cytoplasm occurs.
During mitosis, a single cell divides to produce two genetically identical daughter cells. This process involves several well-defined phases: prophase, metaphase, anaphase, and telophase. Each phase plays a crucial role in ensuring that the chromosomes are replicated accurately and distributed evenly between the two new cells.
Understanding mitosis is essential because it is fundamental to growth, development, and tissue repair in multicellular organisms. It’s how we replace old or damaged cells and is vital in a range of biological processes.
