Chap 6

The regular sequence of growth and division that cells undergo

threadlike structures made of DNA molecules that contain the genes

the relaxed form of DNA in the cell's nucleus

Division of the cytoplasm during cell division

A cellular protein that occurs in a cyclically fluctuating concentration and that plays an important role in regulating the cell cycle.

enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle

A disease in which some body cells grow and divide uncontrollably, damaging the parts of the body around them.

A cancer-causing substance

programmed cell death

unspecialized cells that are able to renew themselves for long periods of time by cell division

period of the cell cycle between cell divisions and normal cell function takes place. 90% of the cell cycle

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

second phase of mitosis, during which the chromosomes line up across the center of the cell

the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles

the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles

the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
