Across
- 4. long strands of DNA found in the eukaryotic cell nucleus; condenses to form chromosomes
- 10. where cell increase in size, replicates DNA, and prepares for cell division
- 11. a protein that regulates the cell cycle
- 14. final stage of nuclear division; new nuclear membrane reforms
- 16. cancer cells that form in a mass
- 17. a process of programmed cell death
- 18. the inner mass of cells; can develop into any cell type
- 20. period following mitosis in which the cell's cytoplasm divides and separates into new cells
- 22. reproduction that produces clones of parent cell
- 23. period of nuclear cell division in which 2 identical daughter cells are formed
Down
- 1. a developmental stage in which 1 cell becomes many
- 2. a stage in human development when specialization has begun
- 3. the process by which cells become specialized
- 5. has the ability to develop into any type of cell in the body
- 6. are unspecialized cells from which different cells develop
- 7. cell structure that joins two sister chromatids of a duplicated chromosome
- 8. period of mitosis where the duplicated chromosomes line up on the equator of the cell and attach to spindle fibers
- 9. found only in animal cells; composed of microtubules and holds spindle fibers during mitosis
- 12. cell structure that carries genetic material that is copied and passed to offspring
- 13. adult stem cells that can replace cells but are limited to one location
- 15. first and longest phase of mitosis where chromatin coils into visible chromosomes
- 19. phase in which the centromeres split and pull chromatids to opposite poles of the cell
- 21. reproduction that increases genetic diversity; 2 parents
