cell division-The process by which a cell divides to form two daughter cells. Upon completion of the process, each daughter cell contains the same genetic material as the original cell and roughly half of its cytoplasm.
chromatid- One of two identical chromosomal strands into which a chromosome splits longitudinally preparatory to cell division.
centromere- The most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.

interphase- the period of the cell cycle during which the nucleus is not undergoing division, usually occurring between mitotic or meiotic divisions.
cell cycle- The series of events involving the growth, replication, and division of a eukaryotic cell.
mitosis- cell division in which the nucleus divides into nuclei containing the same number of chromosome
prophase- Cell Biology. the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
centriole- One of two cylindrical cellular structures that are composed of nine triplet microtubules and form the asters during mitosis.
spindle- a spindle-shaped structure, composed of microtubules, that forms near the cell nucleus during mitosis or meiosis and, as it divides, draws the chromosomes to opposite poles of the cell.
metaphase- the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle.
anaphase- The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle.
telophase- The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
cytokinesis- The division of the cytoplasm of a cell following the division of the nucleus.
cyclin- any of a group of proteins active in controlling the cell cycle and in initiating DNA synthesis
