is mediated by microtubule transport directed to the basolateral versus the apical plasma membranes.

is catalyzed by import and export receptor-FG repeat interactions through the nuclear pore complex.

(A) Diagram the structure of the nucleus. Indicate the aspects important for nuclear-cytoplasmic compartmentalization and transport. (2 pts.) (B) Diagram the general structure of the nuclear pore complex. (2 pts.) (C) Diagram the functional role of the phenylalanine-glycine repeats (FG repeats) in facilitating the passage of nuclear import/export receptor passage through the nuclear pore complex.  Do the FG repeats function to change the
