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)
- They create tension at the kinetochores.

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.
