| cell cycle | regular pattern of growth, DNA duplication, and cell division |
| mitosis | the division of the cell nucleus and its content |
| cytokinesis | the process that divides the cell cytoplasm |
| chromosome | long continuous thread of DNA |
| histone | protein that organizes chormosomes |
| chromatin | loose combination of DNA and proteins |
| centromere | region of the condensed chromosome that looks pinched |
| telomeres | sequence of repeating nucleotides that do not form genes |
| prophase | first phase of mitosis, chromosomes condenses |
| metaphase | second phase of mitosis, chromosomes line at the equator |
