The document discusses cell replication through cell division. It explains that eukaryotic cell division consists of mitosis and cytokinesis. Mitosis involves five phases - prophase, prometaphase, metaphase, anaphase and telophase. During cell division, the genetic material (DNA) is replicated and the chromosomes condense and separate. Cytokinesis then divides the cytoplasm, forming two daughter cells that are genetically identical to the original cell. The document also discusses the cell cycle and its regulation by cyclins and cyclin-dependent kinases. Cancer cells lose cell cycle control and do not respond to regulatory signals.
