| A | B |
| Cell cycle | lifespan of a cell |
| Cell | simplest unit of life |
| Metaphase | chromosomes at middle of cell |
| Mitosis | process when a cell divides into 2 |
| S phase | DNA is replicated; occurs once |
| Cancer | uncontrolled cell growth |
| Chromosome | "X" . contains DNA |
| G1 | "baby" cell begins to grow |
| Telophase | chromosomes far apart |
| Interphase | longest phase in the cell cycle |
| Haploid | means 1/2 normal DNA in cell |
| Centromere | holds chromosome together |
| Anaphase | chromatids move apart |
| Diploid | 2 copies of each chromosome |
| Cytokinesis | when 1 cell splits into 2 cells |
| Prophase | DNA 1st becomes visible |
