Chapter 10 Vocabulary Review
Across
- 3. Substance that causes cancer; chemicals that mutate DNA.
- 5. Production of offspring inherit some of their genetic information from each parent.
- 6. Threadlike structure of DNA and protein that contains genetic information.One long thread of DNA that is tightly coiled in the nucleus.
- 8. Protein that regulate the timing of the cell cycle.
- 9. Protein that stimulates the GROWTH and division of cells during the cell cycle.
- 10. Mass of cancer cells that can be malignant (spreads) or benign (remains at original site).
- 12. One of two identical “sister” parts of a duplicated chromosome.Half of a chromosome.
- 13. First main part of the cell cycle consisting of G1, S, G2. Period of cell growth, replication of DNA, and preparation for division.
- 15. First phase of mitosis in which the cell’s genetic material condenses into chromosomes; nucleus disappears, and the spindle apparatus forms.
- 17. Center of a chromosome where the two sister chromatids attach.
- 18. Programmed cell death that happens when a cell recognizes it isn’t functioning properly.
- 21. Production of genetically identical offspring from a single parent.
- 23. Organelle in an animal cell that helps to organize cell division.
- 24. Series of events in which cells grow, prepare for division, and divide to form two daughter cells. Consists of 3 main parts that continually repeat in eukaryotic cells.
Down
- 1. Unspecialized cells that can develop into specialized cells when under the right conditions.
- 2. Process in which cells become specialized into DIFFERENT types of cells.
- 4. Second main part of the cell cycle which involves the division of the nucleus.
- 6. Relaxed form of DNA in the cell’s nucleus; DNA and proteins.Looks like spaghetti :).
- 7. Second phase of mitosis in which chromosomes line up across the MIDDLE of the cell.
- 11. Process by which an entire cell divides into two new daughter cells.
- 14. Early developmental stage which eventually produces an adult organism.
- 16. Third phase of mitosis in which sister chromatids are pulled apart & move to opposite poles of cell.
- 19. Third main part of the cell cycle that involves the division of the cytoplasm which produces two new daughter cells.
- 20. Fourth and final phase of mitosis in which the chromosomes are at the poles and they relax to form chromatin; nuclear membranes and nucleoli reappear; spindle apparatus breaks down.
- 22. Disorder caused by uncontrolled growth & division of cells; failure in regulation of the cell cycle.
