NAME ______________________________ MITOSIS 10-1 & 10-2 ?’s (pp 240-249) MULTIPLE CHOICE: Circle the letter of the answer that best completes the statement. 1. DNA that is spread out in a non-dividing cell is called _____________________. A. chromosomes B. chromatin 2. The two copies of each chromosome that are the same size, same shape, and carry genes for the same traits are called ___________________________ chromosomes. A. maternal B. paternal C. heterozygous D. homologous 3. Bacteria reproduce using ______________________. A. mitosis B. meiosis C. binary fission D. binary duplication 4. The two chromatid arms on a chromosome are ____________________. A. identical copies B. similar but not identical 5. Homologous chromosomes are _____________________. A. identical copies B. similar but not identical 6. Cells spend most of their lifetime in _____________________ phase of interphase. A. Mitosis B. S C. G1 D. G2 MATCHING: Match the vocab word with its definition: _______ 7. The log-shaped structures that appear next to the nucleus during prophase to pull the chromosomes apart A. B. C. D. E. _______ 8. framework of microtubules to which chromosomes attach during cell division which guides them to the poles CHROMATID CENTRIOLE CENTROMERE CENTROSOME SPINDLE _______ 9. constricted area in the middle of a chromosome that holds the two chromatids together ______ 10. region where centrioles are located that helps organize the spindle ______ 11. one of two identical arms that make up a chromosome * * * 12. * * * * * * * * 14. 13. 15. * 16. * * * MATCH THE PHASE WITH WHAT HAPPENS: You CAN use them more than once S G1 G2 G0 Mitosis (M) Cytokinesis (C) _______ 17.

Interphase (I) Prophase (P) Telophase (T) Cytokinesis (C) Anaphase (A) Metaphase (M) _______ 25. DNA is all spread out as chromatin and nuclear membrane is visible _______ 26. DNA scrunches up and chromosomes are first visible _______ 27. Chromosomes line up in middle of cell _______ 28. DNA is copied and cell prepares to divide _______ 29. Chromatid arms separate and move to opposite ends of the cell _______ 30. Nuclear membrane & nucleolus disappear _______ 31. Two nuclei are visible _______ 32. First dividing phase _______ 33. Made up of _______ 34. Centrosomes containing centrioles & spindle fibers appear next to nucleus _______ 35. Cytoplasm is split between two cells _______ 36. Spindle fibers and centrioles disappear _______ 37. Chromosomes unwind into chromatin & nucleus returns G1, S, G2
