Explain how the nonkinetochore microtubules lead to the elongation of the cell during anaphase
What will be an ideal response?
ANSWER: Two different mechanisms are responsible: 1) the motor proteins walk in opposite directions
along overlapping nonkinetochore microtubules, which pushes the spindles apart; and 2) the
microtubules grow as they slide along, pushing the poles apart.
