| A | B | 
|---|
| G1 | normal 1st part of interphase in cell cycle | 
| S | 2nd step in interphase cell cycle, DNA replication begins | 
| G1, S and then? | G2 | 
| prophase | chromosomes "pairs" first visible | 
| metaphase | chromosomes line up in the middle | 
| anaphase | sister chromatids separate , move apart | 
| telophase | 2 nuclear membranes begin to form | 
| cytokinesis | cutting in half of the cytoplasm | 
| mitosis | occurs in the nucleus only | 
| cell plate | plant cells have this during cytokinesis instead of a cell wall | 
| cleavage furrow | animal cell cytokinesis, cytoplasm pinches in | 
| spindle fibers | push and pull chromosomes around dring mitosis | 
| chromatin | thin strands of genetic material that will form chromosomes | 
| 2 identical cells | goal of the mitosis process | 
| interphase | cells spend most their time in this phase |
