Cellular Reproduction

1. process of cellular reproduction, occurring in three main stages
2. last stage of mitosis, in which nucleoli reappear; two new nuclear membranes begin to form, but the cell has not yet completely divided
5. uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and may also be caused by environmental factors
10. third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromasomes to opposite poles of the cell
11. structure that contains identical DNA copies and is formed during DNA replication
13. the first stage of mitosis, during which the cell's chromatin condenses into chromasomes
14. DNA-containing structure that carries genetic material from one generation to another
15. one of the specific proteins that regulate the cell cycle
17. enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle

1. cell structure that joins two sister chromatids
3. programmed cell death
4. second stage of mitosis in which motor proteins pull sister chromatids to the cell's equator
6. repeating subunit of chromatin fibers, consisting of DNA coiled around histones
7. second main stage of the cell cycle, during which the cell's replicated DNA divides and two genetically identical diploid daughter cells are produced
8. structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromasomes before the cell divides
9. cancer-causing substance
12. relaxed form of DNA in the nucleus of a cell
15. third main stage of the cell cycle, during which the cell's cytoplasm divides, creating a new cell
16. first stage of the cell cycle, during which a cell grows, matures, and replicates its DNA
