Across 3. complex of proteins associated with the centromere of a chromosome during cell division 6. organelle near the nucleus of a cell that contains the centriole,spindle fibers develop in cell division. 7. formed around each centrosome during mitosis in an animal cell 12. removal of a nucleus, which contains the genetic material, 16. chromosomes of organisms are composed. It consists of protein, RNA, and DNA. 17. ylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. 18. stage of mitosis and of meiosis

Down 1. the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle. 2. involves creating an animal that is genetically identical to a donor animal through somatic cell nuclear transfer 4. final phase of cell division, between anaphase and interphase 5. the second stage of cell division, between prophase and anaphase 8. Cytokinesis in terrestrial plants occurs by cell plate formation. 9. which animal and some algal cells undergo cytokinesis 10. second phase of mitosis, the process that separates the duplicated genetic material 11. region of a chromosome in which the microtubules of the spindle attach,via the kinetochore, during cell division. 13. group of basic proteins found in chromatin. 14. having a single set of unpaired chromosomes. 15. containing two complete sets of chromosomes
