| cell division | process by which a cell divides into two new daughter cells |
| asexual reproduction | process of reproduction involving a single parent that results in offspring that are genetically identical to the parent |
| sexual reproduction | type of reproduction in which cells from two parents unite to form the first cell of a new organism |
| chromosome | threadlike structure of DNA and protein that contains genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes, they are found in the cytoplasm |
| chromatin | substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones |
| cell cycle | series of events in which a new cell grows, prepares for division, and divides to form two daughter cells |
| interphase | period of the cell cycle between cell divisions |
| mitosis | part of eukaryotic cell division during which the cell nucleus divides |
| centromere | region of a chromosome where two sister chromatids attach |
| chromatid | one of two identical “sister” parts of a duplicated chromosome |
| centriole | structure in an animal cell that helps to organize cell division |
| metaphase | phase of mitosis in which the chromosomes line up across the center of the cell |
| anaphase | phase of mitosis in which the chromosomes separate and move to opposite ends of the cell |
| telophase | phase of mitosis in which that distinct individual chromosomes begin to spread out into a tangle of chromatin |
