- 3. having no dangerous effect on health, especially referring to an abnormal growth of cells that are not cancerous
- 4. second phase of mitosis when spindle fibers line up the chromosomes along the cell equator
- 5. programmed cell death
- 9. cancerous tumor in which cells break away and spread to other parts of the body, causing harm to the organism's health
- 10. broad group of proteins that stimulate cell division
- 13. pattern of growth, DNA replication, and cell division that occurs in a eukaryotic cell
- 14. one half of a duplicated chromosome
- 16. repeating nucleotide at the ends of DNA molecules that do not form genes and help prevent the loss of genes
- 17. first phase of mitosis when chromatin condenses, the nuclear envelope breaks down, the nucleolus disappears, and the centrosomes and centrioles move to opposite sides of the cell
- 19. loose combination of DNA and proteins that is present during interphase
- 22. process by which the cell cytoplasm divides
Down
- 1. anaerobic process by which ATP is produced by glycolysis
- 2. third phase of mitosis during which chromatids separate and are pulled to opposite sides of the cell
- 6. substance that causes cancer

- 8. process by which a cell divides its nucleus and contents
- 11. common name for a class of diseases characterized by uncontrolled cell division
- 12. to spread by transferring a disease-causing agent from the site of the disease to other parts of the body
- 15. long, continuous thread of DNA that consists of numerous genes and regulatory information
- 18. part of a condensed chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis
- 20. protein that organizes chromosomes and around which DNA wraps
- 21. last phase of mitosis when a complete set of identical chromosomes is positioned at each pole of the cell, the nuclear membranes start to form, the chromosomes begin to uncoil, and the spindle fibers break apart
