Note:  This question is out of 4 points but I have put ‘0’ points in the score points so that these points go towards your potential extra credit points to account for any question missed by misunderstanding or overthinking, etc.     Briefly describe how cytoskeleton polarity (+ vs – sides), combined with the motor proteins dynein and kinesin contribute to cell polarity such that specific delivery of membrane or secreted proteins to the apical vs. basal sides of the cell can occur.  (4 points)
