| cell cycle | period of time from the beginning of one cell division to the beginning of the next |
| cell division | process in which a cell divides into two independent daughter cells |
| mitosis | process of cell division in eukaryotic cells |
| interphase | G1, S, and G2 phases; occurs between cell divisions |
| prophase | first phase of mitosis during which each chromosome consists of two chromatids |
| chromatids | strand of a chromosome that occurs in identical pairs; combined with its sister chromatid, constitutes a chromosome |
| centromere | the part of a chromosome in which the chromatids are attached |
| spindle | cluster of microtubules that span the cell nucleus |
| metaphase | second phase of mitosis during which the chromosomes complete their attachment to the spindle and line up across the center of the cell |
| anaphase | third phase of mitosis during which duplicated chromosomes separate from each other |
| telophase | fouth and final phase of mitosis during which two distinct nuclei form within the cell |
| cytokinesis | division of the cytoplasm that takes place during the anaphase and telophase phases of mitosis in most cells |
