Mitosis Study Guide
| Question | Answer |
|---|---|
| Chromosomes are copied (# doubles) | INTERPHASE |
| Chromosomes appear as threadlike coils (chromatin) at the start, but each chromosome and its copy (sister chromosome) change to sister chromatids at end of this phase | INTERPHASE |
| Mitosis begins (cell begins to divide) | PROPHASE |
| Centrioles (or poles) appear and begin to move to opposite ends of cell | PROPHASE |
| Spindle fibers form between the poles | PROPHASE |
| Chromatids (or pairs of chromosomes) attach to the spindle fibers | METAPHASE |
| Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell | ANAPHASE |
| Two new nuclei form | TELOPHASE |
| Chromosomes appear as chromatin (threads rather than rods) | TELOPHASE |
| Mitosis ends | TELOPHASE |
| Cell membrane moves inward to create two daughter cells - each with its own nucleus with identical chromosomes | CYTOKINESIS |
