Cell Division
Process by which a cell divides into two new daughter cells.
Mitosis
Part of eukaryotic cell division during which the cell nucleus divides.
Cytokinesis
Division of the cytoplasm during cell division.
Chromatid
One of two identical "sister" parts of a duplicated chromosome.
Centromere
Area where the chromatids of a chromosome are attached.
Interphase
Period of the cell cycle between cell divisions.
Cell Cycle
Series of events that cells go through as they grow and divide.
Prophase
First and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus.
Centriole
One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope.
Spindle
Fanlike microtubule structure that helps separate the chromosomes during mitosis.
Metaphase
Second phase of mitosis, during which the chromosomes line up across the center of the cell.
Telophase
The third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles.
Anaphase
Fourth and final phase of mitosis, during which the chromosomes begin to disperse into a tangle of dense material.
Cyclin
One of a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
Cancer
Disorder in which some of the body's own cells lose the ability to control growth.
