Across
- 2. one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells
- 3. 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
- 6. one of a group of external regulatory proteins that stimulate the growth and division of cells
- 8. unspecialized cell that can give rise to one or more types of specialized cells
- 9. stem cells with the potential to differentiate into any type of cell
- 11. A reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents
- 12. cell division in which the nucleus divides into
- 13. period of the cell cycle between cell divisions
- 14. second phase of mitosis, during which the chromosomes line up across the center of the cell
- 17. an organism in the earliest stage of development
- 18. Cells that are capable of developing into most, but not all, of the body's cell types
- 20. division of the cytoplasm during cell division
- 21. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
- 22. any malignant growth or tumor caused by abnormal and uncontrolled cell division
- 24. Clusters of DNA, RNA, and proteis in the nucleus of a cell
- 25. on of two identical "sister" parts of a duplicated chromosome
- 26. Chromosome become visible, nuclear envelop dissolves, spindle forms
Down
- 1. Area where the chromatids of a chromosome are attached
- 2. series of events that cells go through as they grow and divide
- 4. process in which cells become specialized in structure and function
- 5. stage of early development in mammals that consists of a hollow ball of cells
- 7. programmed cell death
- 10. cell organelle that aids in cell division in animal cells only
- 15. process by which a single parent reproduces by itself
- 16. cell with limited potential to develop into many types of differentiated cells
- 19. mass of rapidly dividing cells that can damage surrounding tissue
- 22. process by which a cell divides into two new daughter cells
- 23. the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
