Across
  1. 2. one of two identical “sister” parts of a duplicated chromosome
  2. 5. repetitive DNA at the end of a eukaryotic chromosome
  3. 7. type of bond between atoms in which the electrons are shared
  4. 8. division of the cytoplasm to form two separate daughter cells
  5. 9. mass of rapidly dividing cells that can damage surrounding tissue
  6. 14. Pairs with Guanine
  7. 16. subunit of which nucleic acids are composed; made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base
  8. 17. developing stage of a multicellular organism
  9. 18. region of a chromosome where the two sister chromatids attach
  10. 19. phase of mitosis/Meiosis in which the chromosomes/chromatids separate and move to opposite ends of the cell
  11. 20. type of reproduction in which cells from two parents unite to form the first cell of a new organism
  12. 22. Adenine, Thymine, Cytosine and Guanine are all examples of this
  13. 27. phase of mitosis/meiosis in which the chromosomes line up across the center of the cell
  14. 29. structure in an animal cell that helps to organize cell division
  15. 30. A pairs with T and C pairs with G
  16. 32. sequence of DNA that codes for a protein and thus determines a trait; factor that is passed from parent to offspring
  17. 34. phase of mitosis/meiosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
  18. 36. process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
  19. 37. principle enzyme involved in DNA replication
  20. 38. series of events in which a cell grows, prepares for division, and divides to form two daughter cells
  21. 39. part of eukaryotic cell division during which the cell nucleus divides
  22. 40. the shape of DNA
Down
  1. 1. process in which cells become specialized in structure and function
  2. 3. 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)
  3. 4. stage of early development in mammals that consists of a hollow ball of cells
  4. 6. cell with limited potential to develop into many types of differentiated cells
  5. 7. threadlike structure within the nucleus that contains genetic information that is passed on from one generation to the next
  6. 10. disorder in which some of the body's cells lose the ability to control growth
  7. 11. principle that bonds in DNA can form only between adenine and thymine and between guanine and cytosine
  8. 12. weak attraction between a hydrogen atom and another atom
  9. 13. one of a group of external regulatory proteins that stimulate the growth and division of cells
  10. 15. entire set of genetic information that an organism carries in its DNA
  11. 21. process of copying DNA prior to cell division
  12. 23. Pairs with Adenine
  13. 24. period of the cell cycle between cell divisions in which the cell grows
  14. 25. first and longest phase of mitosis/meiosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
  15. 26. cells that are capable of developing into most, but not all, of the body's cell types
  16. 28. Pairs with Thymine
  17. 31. the process of programmed cell death
  18. 32. Pairs with Cytosine
  19. 33. substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
  20. 35. unspecialized cell that can give rise to one or more types of specialized cells
