  1. 5. the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.
  2. 7. the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
  3. 8. the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle
  4. 10. a swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant.
  5. 12. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
  6. 13. stores DNA

  1. 1. very virulent or infectious.
  2. 2. the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
  3. 3. a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
  4. 4. harmful to health
  5. 6. the action or process of transcribing something.
  6. 9. a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
  7. 11. the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
