TermDefinition
MitosisThe process by which the nucleus and duplicated chromosomes of a cell divide and are evenly distributed, forming two daughter nuclei.
MeiosisA type of cell division that produces four cells, each with half as many chromosomes as the parent cell.
ChromosomeCondensed threads of genetic material formed from chromatin as a cell prepares to divide.
Homologous ChromosomeOne of a matching pair of chromosomes, one inherited from each parent.
ChromatinThe combination of DNA and protein molecules, in the form of long, thin fibers, making up the genetic material in the nucleus of a eukaryotic cell.
ChromatidEach of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
Sister ChromatidOne of a pair of identical chromosomes created before a cell divides.
CentromereRegion where two sister chromatids are joined tightly together.
CentrioleOrganelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
CentrosomeRegion of cytoplasmic material that in animal cells contains structures called centrioles.
GeneThe unit of inherited information in DNA.
DiploidHaving two homologous sets of chromosomes.
HaploidHaving a single set of chromosomes.
