Explain/Teach these Concepts to a Friend

Explain why a cell’s DNA is long, why it is only slightly compacted during interphase, but must become significantly condensed for the cell to be able to segregate its chromosome successfully.

Explain why the metaphase spindle is 2-fold symmetric.

Explain why microtubules are polar structures, not themselves 2-fold symmetric.

Explain why the system of using tension at the kinetochore-microtubule junction is an effective one for assuring that chromosomes are properly segregated during anaphase.

Explain why anaphase generally includes both Anaphase-A (the chromosomes approach the spindle poles) and Anaphase-B (the spindle poles move apart).
