  5. The second part of interphase is called ____________.

    D. replication
  6. ________________ is the process by which the DNA makes an identicalcopy of itself.

    C. replication
  7. _____________ is the stage in which the cell's nucleus divides into two new nuclei.

    A. Mitosis
  8. The mitosis phase is divided into ________ parts.

    A. four

  9. During ____________, one copy of the DNA is distributed to each of the two daughter cells.

    D. mitosis
  10. The final stage of the cellcycle is ____________.

    e. duplicaiton
    A. cytokinesis
  11. During this stage of the cell cycle, the cytoplasm divides, distributing the organelles into each of the two new cells.

    C. cytokinesis
  12. During cytokinesis in an animal cell, the ______________ squeezes together and then pinches off to form the two new cells.

    C. cell membrabe
  13. Since a plant has a rigid cell wall, cytokinesis is accomplished when a __________ cell plate forms in the middle of the town new cells.

    A. cell plate
  14. DNA carries all the cell's instructions.

  15. DNA is passed from a parent cell to its ________ cell.

    B. daughter
  16. DNA looks like a(n) ________________.

    C. twisted ladder
  17. The twisted ladder of DNA is called a _______________.

    C. double helix

  29. New DNA molecules are created from the unzipped DNA when _________ bases attach to the open sides of the DNA ladder.

    D. nitrogen
  30. When both unzipped DNA strands are paired up with the nitrogen bases two identical DNA molecules have been formed.
