Across
- 4. any change in the DNA sequence
- 6. agent with the capacity to cause cancer in humans
- 7. threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
- 10. division of the cytoplasm to form two separate daughter cells
- 12. first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
- 14. cell–unspecialized cell that can give rise to one or more types of specialized cells
- 15. reproduction type of reproduction in which one parent cell produces two identical offspring (daughter cells)
- 17. therapy--the treatment of disease, especially cancer, using X-rays or similar forms of radiation.
- 18. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
- 20. phase of mitosis in which the chromosomes line up across the center of the cell
- 21. tumor, or growth that is not cancerous (does not spread into nearby tissues)
- 24. stage of early development in mammals that consists of a hollow ball of cells
- 26. a fertilized egg
- 27. the development of secondary malignant growths at a distance from a primary site of cancer
- 28. process in which cells become specialized in structure and function
- 29. reproduction type of reproduction in which cells from two parents unite to form the first cell of a new organism
- 30. cell with limited potential to develop into many types of differentiated cells
Down
- 1. disorder in which some of the body's cells lose the ability to control growth
- 2. the presence of cancerous cells that have the ability to spread to other sites in the body (metastasize) or to invade nearby (locally) and destroy tissue
- 3. drug treatment that uses powerful chemicals to kill fast-growing cells in your body
- 5. growth of new blood vessels that tumors need to grow
- 8. one of a family of proteins that regulates the cell cycle in eukaryotic cells
- 9. cells that are able to develop into any type of cell found in the body (including the cells that make up the extraembryonic membranes and placenta)
- 10. cycle series of events in which a cell grows, prepares for division, and divides to form two daughter cells
- 11. period of the cell cycle between cell divisions in which the cell grows
- 13. developing stage of a multicellular organism
- 15. the process of programmed cell death
- 16. phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
- 19. region of a chromosome where the two sister chromatids attach
- 22. cells that are capable of developing into most, but not all, of the body's cell types
- 23. one of two identical "sister" parts of a duplicated chromosome
- 24. fission type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
- 25. treatment that uses certain parts of a person's immune system to fight diseases such as cancer
- 31. phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
