| Feature | Karyokinesis | Cytokinesis |
|---|---|---|
| What divides | The nucleus | The cytoplasm |
| Sequence | Occurs first (comprises prophase, metaphase, anaphase, telophase) | Occurs after karyokinesis is complete (usually overlapping with telophase) |
| Outcome | Produces two genetically identical (or, in meiosis, recombined/haploid) daughter nuclei within the same cell | Physically separates the cell into two independent daughter cells, each receiving one of the new nuclei |
| Mechanism | Chromosome condensation, spindle formation, and segregation of chromosomes/chromatids to opposite poles | In animal cells, a cleavage furrow pinches the cell membrane inward; in plant cells, a cell plate forms in the middle and grows outward to divide the cell |
