Question	Answer
Cell cycle	process of cellular reproduction, occurring in three main stages
Chromatin	relaxed form of dna in the nucleus of a cell
Chromosome	dna-containing structure that carries genetic material from one generation to another
Cytokinesis	third main stage of the cell division by stimulating production of proteins required for mitosis
Interphase	first stage of the cell cycle, during which a cell grows, matures and replicates its dna
Mitosis	second main stage of the cell cycle during which the cell's replicate dna divides and two genetically identical diploid daughter cells are produced
Anaphase	third stage of mitosis in which sister chromatids are pulled apart and microtublues, along with motor proteins move the chomosomes to opposite poles of the cell
Centromere	cell structure that joins two sister chromatids
Metaphase	second stage of mitosis in which motor proteins pull sister chromatids to the cell's equator
Prophase	first stage of mitosis, during which the cell's chromatin condenses into chromosomes
Sister chromatid	structure that contains identical dna copies and formed during dna replication
Spindle apparatus	structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides
Telophase	last stage of mitosis in which nucleoli reappear. Two new nuclear memberanes begin to form, but the cell has not yet completely divided
Apoptosis	programmed cell death
Cancer	uncontroled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors
Carcinogen	cancer-causing substance
Cyclin	one of the specific proteins that regulate the cell cycle
Stem cell	unspecialized cell that can develop into a specialized cell under the right conditions
dependent kinase	enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle
