| What is Anaphase? | chromosomes separating |
| What is Telophase/Cytokinesis? | nucleus reappears, cell wall forms, spindle disappears |
| Animal cell mitosis vs. plant cell mitosis | animal mitosis cleavage furrow and plant cells use a cell plate to divide, plant cell=square, animal cell=2 circles |
| what is the job of cyclin and protein kinases? | Cyclins job is to attach to protein kinases to activate them, "lin" means proteins |
| Crossing over? | When chromosomes come physically connected with each other genetic rearrangement occurs |
