Study guide
Mitosis study guide
Mitosis is the nuclear division process that segregates sister chromatids into two nuclei. This hub pairs stage language with explorers and worksheet practice while keeping meiosis clearly separate.
What you will learn
- Mitotic stages used in standard teaching models
- Sister-chromatid segregation versus cytokinesis
- Why chromosomes look condensed in textbook mitosis figures
- Compare mitosis with meiosis intentionally
Core lessons
Start with the primary article, then branch into closely related concepts.
- Mitosis — Mitosis is nuclear division that segregates sister chromatids into two daughter nuclei.
- Prophase — Prophase begins mitosis with chromosome condensation and spindle organization.
- Metaphase — Metaphase aligns chromosomes at the metaphase plate with spindle attachments.
- Anaphase — Anaphase separates sister chromatids toward opposite poles.
- Telophase — Telophase reforms nuclei around separated chromosome sets.
- Cytokinesis — Cytokinesis divides the cytoplasm to produce two daughter cells.
- Cell cycle — The cell cycle is the ordered series of stages a cell passes through to grow and divide.
- Sister chromatids — Sister chromatids are the two identical copies of a duplicated chromosome produced by DNA replication.
- Chromosome condensation — Chromosome condensation is the compaction of chromatin into discrete mitotic or meiotic chromosomes.
Comparisons
- Mitosis vs meiosis — Mitosis preserves chromosome number for growth; meiosis reduces ploidy and increases variation for sexual reproduction.

Glossary terms
Common questions
What is mitosis?
Mitosis is the process of nuclear division that separates duplicated sister chromatids into two genetically equivalent nuclei, typically followed by cytokinesis that divides the cell.
What are the stages of mitosis?
Common teaching stages are prophase (plus prometaphase in many texts), metaphase, anaphase, and telophase, with cytokinesis completing physical cell division afterward.
