Explain/Teach these Concepts to a Friend
Explain why the existence of forces pulling the metaphase chromosomes toward both poles implies that there are also forces pulling the poles toward the spindle midplane.
Explain how two motors with opposite directions of action can work against each other as they cross-bridge the same microtubules.
Describe what is going on when spindle microtubules are fluxing towards the poles.
Explain how the idea of stabilizing the attachment of chromosomes to the spindle by tension allows the cell to select against inappropriate attachments, like the attachment of both kinetochores on one chromosome to a single pole.
Explain how pushing forces from the pole can help to get a prometaphase chromosome to the metaphase plate. |
