Across
  1. 6. - phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
  2. 7. - region of a chromosome where the two sister chromatids attach
  3. 8. - part of eukaryotic cell division during which the cell nucleus divides
  4. 10. - cell with limited potential to develop into many types of differentiated cells
  5. 14. fission - type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
  6. 15. - structure in an animal cell that helps to organize cell division
  7. 19. reproduction - process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
  8. 20. - threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
  9. 21. - mass of rapidly dividing cells that can damage surrounding tissue
  10. 22. cycle - series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  11. 23. -phase of mitosis in which the chromosomes line up across the center of the cell
  12. 24. factor - one of a group of external regulatory proteins that stimulate the growth and division of cells
  13. 27. - first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  14. 28. - the process of programmed cell death
  15. 31. reproduction - type of reproduction in which cells from two parents unite to form the first cell of a new organism
  16. 32. - one of two identical "sister" parts of a duplicated chromosome
  17. 33. - one of a family of proteins that regulates the cell cycle in eukaryotic cells
Down
  1. 1. - substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  2. 2. - disorder in which some of the body's cells lose the ability to control growth
  3. 3. - developing stage of a multicellular organism
  4. 4. - phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  5. 5. - abnormal cells which divide without control and can invade nearby tissues
  6. 9. (fibers) - network of microtubules that forms within a dividing eukaryotic cell; help to move chromosomes into the daughter cells during mitosis
  7. 11. - 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)
  8. 12. - cells that are capable of developing into most, but not all, of the body's cell types
  9. 13. - process in which cells become specialized in structure and function
  10. 16. division (M phase) - process by which a cell divides into two new daughter cells
  11. 17. - unstable form of a chemical element that releases radiation as it breaks down which can damage cells; used to diagnose and treat some types of cancer
  12. 18. - period of the cell cycle between cell divisions
  13. 20. - division of the cytoplasm to form two separate daughter cells
  14. 25. cell - unspecialized cell that can give rise to one or more types of specialized cells
  15. 26. - treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing
  16. 29. - stage of early development in mammals that consists of a hollow ball of cells
  17. 30. - an abnormal, but non-cancerous collection of cells which do not invade other sites of the body
