Across

4. having a single set of unpaired chromosomes

5. assembly of protiens that attaches to the centromere of a chromosome during mitosis

6. the material of which the chromosomes of organisms other than bacteria (eukaryotes) are composed. (protein, RNA, and DNA)

9. any of a group of basic proteins found in chromatin.

12. Area where the chromatids of a chromosome are attached

15. second phase of mitosis: chromosomes are condense but not full aligned at the metaphase plate

16. Cell finishes dividing, chromosomes lengthen and become thinner, nuclear membrane reappears, cytoplasm gets divided up evenly

17. short, radiating fibers produced by the centrosomes in the animal cells

19. the nucleus of a cell is inserted into a fertilized egg whose nucleus has been removed.

Down

1. Chromosomes become visable, nuclear envelop dissolves, spindle forms

2. central microtubule organizing center of cells

3. he genetic duplication of an existing organism by transferring the nucleus of a somatic cell of the organism into an enucleated oocyte

7. Centromeres of duplicated chromosomes are aligned at plate. Fully formed spindle attach to the sister chromatids from opposite poles

8. occurs in the centrosome and may help organize a mitotic spindle for movement during cell division

10. the final splitting of the membrane, in the process of cell division.

11. a plane or region that is approximately equidistant from the two poles of a dividing cell.

13. Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell

14. cell structure that surrounds a

18. containing two complete sets of chromosomes, one from each parent.
