| cell cycle | the regular sequence of growth and division cells undergo |
| interphase | the period before cell division |
| mitosis | the process by which a cell makes a copy of the DNA in its nucleus |
| replication | the stage during which the cell's nucleus divides into two new nuclei |
| chromosome | composed of two chromatids bound by a cetromere |
| cytokinesis | stage during which the cytoplasm divides and organelles are distributed into each of the two new cells |
| prophase | chromatin condense to form chromosomes, spindle fibers form, nuclear envelope breaks down |
| metaphase | chromosomes line up across the center of the cell and attache to spindle fiber at its centromere |
| anaphase | centromeres split, chromatids separate and move to opposite ends of the cell |
| telophase | chromosomes stretch out and lost rodlike appearance; new nuclear envelope forms |
