Mitosis Flashcards
| Question | Answer |
|---|---|
| Interphase | -Interphase is the 'resting' phase of the cell cycle where most of the cell's life takes place. -Chromosomes are uncondensed and appear as chromatin during interphase. -DNA replication occurs in interphase, preparing for cell division. |
| Prophase | -Chromosomes condense and become visible as X-shaped structures in prophase. -The nuclear envelope begins to break down during prophase. -Spindle fibers form in prophase, preparing to separate the chromosomes. |
| Metaphase | -Chromosomes align in the center of the cell at the 'metaphase plate' during metaphase. -Spindle fibers attach to the centromeres of each chromosome in metaphase. -Metaphase is the most organized stage of mitosis. |
| Anaphase | -Spindle fibers pull sister chromatids apart towards opposite poles of the cell in anaphase. -The cell begins to elongate as the chromosomes separate during anaphase. -Anaphase is the shortest stage of mitosis. |
| Telophase | -Nuclear envelopes reform around the separated chromosomes in telophase, forming two daughter nuclei. -Chromosomes decondense and become less visible in telophase. -The cell prepares for Cytokinesis during telophase. |
| Cytokinesis | The cell membrane pinches in, dividing the cytoplasm into two daughter cells during cytokinesis. Each daughter cell receives a complete set of chromosomes in cytokinesis. Mitosis is complete after cytokinesis-two genetically identical daughter cells. |
