| A | B |
| cell cycle | the cycle of growing and dividing that eukaryotic cells do |
| interphase | main stage of cell cycle in which cell grows and copies DNA |
| mitosis | main stage of cell cycle where nucleus divides |
| cytokinesis | divides the cytoplasm |
| chromosomes | condensed DNA |
| chromatin | relaxed form of DNA in nucleus |
| binary fission | method by which prokaryotic cells divide |
| prophase | first stage of mitosis |
| metaphase | shortest stage of mitosis |
| anaphase | third stage of mitosis |
| telophase | final stage of mitosis |
| sister chromatids | structures that contain identical copies of DNA |
| centromere | structure at center of chromosome where chromatids are attatched |
| spindle apparatus | network of spindle fibers, centrioles, and aster fibers |
| centriole | bundle of cytoskeleton which forms the "pole" |
| motor protein | pull chromatids along spindle fibers |
| furrow | wrinkle or pinch where cytoplasm will divide. |
| homologous | 2 identical chromosomes |
| gamete | sex cell |
| stages of mitosis | prophase, metaphase, anaphase and telophase |
| how many divisions take place in one cycle of meiosis | 2 |
| haploid | sperm or egg cell; 1/2 the full set of chromosomes |
| diploid | full set of chromosomes; skin cells |
| replication | making a complete copy of the DNA |
| what happens during "cross over" | pieces of homologous chromosomes exchange info during prophase 1 |
