| A | B |
| Telomere | End of a chromosome containing repeated DNA sequences |
| Prophase | Stage of division in which chromosomes condense, spindle forms |
| Cell Cycle Mutants | Mutations that interupt the normal life history of a cell |
| Enzyme | Protein that speeds up a reaction |
| Nondisjunction | Failure of a chromosome to seperate correctly, resulting in daughter cells that have one less or one more than chromosome than normal |
| Chiasma | Structure observed after non-sister chromatids cross and exchange genetic segments during meiosis |
| Homologous | This describes chromosomes that look alike at mitotic metaphase, carry the same genes, and pair during meiosis |
| Cytokinesis | Division of cytoplasm that results in two daughter cells |
