Term | Definition |
chromosome | threadlike structure of DNA and protein that contains genetic info; in eukaryotes, 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 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 |
cytokinesis | division of the cytoplasm to form two separate daughter cells |
prophase | genetic material inside the nucleus condenses and duplicated chromosomes become visible |
centromere | region of a chromosome where the two sister chromatids attach |
chromatid | one of the two identical "sisters" parts of a duplicated chromosome |
centriole | structure in an animal cell that helps organize cell divison |
metaphase | chromosomes line up at the center of the cell |
anaphase | chromosomes move toward opposite poles |

asexual reproduction | process of reproduction involving a single parent that results in offspring that are genetically identical to the parent |
