Mitosis Stages and Cell Division

In 1855, Rudolf Virchow, a German scientist, observed that all cells come from other cells, forming the basis of cell theory. This implies that cells can replicate themselves. Mitosis is the process by which a cell divides its nucleus into two, ensuring genetic material is copied accurately. Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.
