Cell Cycle An ordered sequence of events in the life of a cell Mitosis A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei. Cytokinesis The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II. Cell Division The reproduct...
