Questions and Answers

What is the role of non-kinetochore microtubules during cell division?

  • They assist in chromosome alignment.
  • They facilitate the formation of daughter nuclei.
  • They help elongate the cell by pushing against each other. (correct)

    Study Notes

    Cell Division: Telophase and Cytokinesis

    • Non-kinetochore microtubules from opposite poles overlap, pushing against each other, lengthening the cell.
    • In telophase, genetically identical daughter nuclei form at opposite cell ends.
    • Cytokinesis starts during anaphase or telophase. The spindle eventually breaks down.
    • In animal cells, cytokinesis involves cleavage, forming a cleavage furrow.
    • Plant cells form a cell plate during cytokinesis.
