Bio/Int. 2- Lesson 8
Mitosis
| Term | Definition |
|---|---|
| Cell Cycle | a series of events a cell goes through as they grow and divide |
| Mitosis | the process of forming identical daughter cells by replicating and dividing the original chromosomes |
| Interphase | longest phase of the cell cycle, during which the cell grows, copies its DNA, and prepares for cell division |
| Prophase | phase of mitosis where the chromosomes coil up and become visible, the nuclear envelope dissolves, and the spindle fibers form |
| Metaphase | phase of mitosis where the chromosomes move to the center of the cell and line up along the equator, spindle fibers link the chromatids of each chromosome to opposite poles |
| Anaphase | phase of mitosis where the centromeres of chromosomes divide, the two chromatids move toward opposite poles as the spindle fibers attach to them shorten |
| Telophase | phase of mitosis where a nuclear envelope forms around the chromosomes at each pole, chromosomes then uncoil and the spindle fibers dissolve and disappear |
| Cytokinesis | the splitting of the cell’s cytoplasm to form two new cells |
| Centriole | a tiny structure within a cell that functions to organize the spindle fibers during mitosis |
| Spindle Fibers | microfibers that help to separate chromosomes during the process of mitosis |
