| A | B |
|---|
| cytokinesis | division of the cytoplasm |
| metaphase | chromosome settles midway between the two poles |
| mitotic spindle | fibers composed of microtubules |
| prophase | chromosomes are tightly coiled |
| G2 phase | the cell completes preparations for cell division |
| S phase | the chromosomes are copied |
| G1 phase | centered on growth |
| Interphase | accounts for 90% of the cell cycle |
| mitotic (M) phase | includes mitosis and cytokinesis |
| centromere | where the sister chromatids connect |
| chromatin | DNA-protein complex |
| gametes | sex cells (N) |
| somatic cells | body cells (2N) |
| chromosomes | DNA molecules are packaged into |
| genome | A cell’s genetic information |
| Cell division | DNA - to two daughter cells. |
| anaphase | chromosomes are pulled apart |
| telophase | nuclei are forming, cytokinesis begins |
| centrioles | move spindle fibers |
| aster | star-like appearance of spindle fibers |
