Chapter 17
Across
- 2. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
- 5. cells with limited potential to develop into many types of differentiated cells
- 7. process by which cells become specialized in structure and function
- 9. threadlike structure of SNA and protein that contains genetic information
- 11. structure of an animal cell that helps to organize cell division
- 12. first and longest phases of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
- 15. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
- 17. region of a chromosome in which the two sister chromatids attach
- 18. one of two identical “sister” parts of a duplicated chromosome
Down
- 1. unspecialized cell that can give rise to one or more types of specialized cells
- 3. stage of early development in mammals that consists of a hollow ball of cells
- 4. phase of mitosis in which the chromosomes line up across the center of the cell
- 6. part of eukaryotic cell division during which the cell nucleus divides
- 8. process of programmed cell death
- 10. mass of rapidly dividing cells that can damage surrounding tissue
- 13. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
- 14. period of the cell cycle between cell divisions
- 16. division of the cytoplasm to form two separate daughter cells
