Cell Division- the division of a cell in reproduction or growth Chromatid- one of two identical strands into which a chromosome splits during mitosis
Centromere- The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis Interphase- The stage of a cell between two successive mitotic or meiotic divisionsCell Cycle- The series of events involving the growth, replication, and division of a eukaryotic cell
Mitosis- The entire process of cell division including division of the nucleus and the cytoplasmProphase- the first stage of meiosis and mitosis
Centriole- One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosisSpindle- tiny fibers that are seen in cell division; the fibers radiate from two poles and meet at the equator in the middle; "chromosomes are distributed by spindles in mitosis and meiosis"

Metaphase- the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindleAnaphase- the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cellTelophase- the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes
Cytokinesis- the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus Cyclin- A class of proteins that fluctuate in concentration at specific points during the cell cycle and that regulate the cycle by binding to a kinase

Cancer- disorder in which some of the body's own cells lose the ability to control growth
