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