Across
- 2. Developing stage of a multicellular organism
- 4. Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
- 6. One of a group of external regulatory proteins that stimulate the growth and division of cells
- 10. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
- 15. Period of the cell cycle between cell divisions in which the cell grows
- 16. The process of programmed cell death
- 17. Cells that are able to develop into any type of cell found in the body (including cells that make up the extraembryonic membranes and placenta)
- 18. Phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
- 19. Stage of early development in mammals that consists of a hollow ball of cells
- 25. Process in which a cell divides into two new daughter cells
- 27. Cells that are capable of developing into most, but not all, of the body’s cell types
- 28. Mass of rapidly dividing cells that can damage surrounding tissue
Down
- 1. Type of reproduction in which cells from two parents unite to form the first cell of a new organism
- 3. Division of the cytoplasm to form two separate daughter cells
- 5. unspecialized cell that can give rise to one or more type of specialized cells
- 7. Region of a chromosome where the two sister chromatids attach
- 8. One of two identical “sister” parts of a duplicated chromosome
- 9. Process in which cells become specialized in structure and function
- 11. Threadlike structure within the nucleus that contains genetic information that is passes on from one generation to the next
- 12. Series of events in which a cell grows, prepares for division, and divides to form two daughter cells
- 13. Phase of mitosis in which the chromosomes line up across the center of the cell
- 14. Part of eukaryotic cell division during which the cell nucleus divides
- 20. One of a family of proteins that regulates the cell cycle in eukaryotic cells
- 21. Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
- 22. cell with limited potential to develop into many type of differentiated cells
- 23. Disorder in which some of the body’s cells lose the ability to control growth
- 24. Structure in an animal cell that helps to organize cell division
- 26. First and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
