According to the model for nuclear transport described in this chapter, what do you think would happen if you could artificially limit all Ran-GAP activity to the nucleus and all Ran-GEF activity to the cytosol?

A) Proteins containing an NLS would be actively exported from the nucleus, while NES-containing proteins would be actively imported.
B) Both import and export of nuclear proteins would be stalled, as they lose their directionality.
C) Protein import into the nucleus would be reversed, but export would be unaffected.
D) Protein import into the nucleus would be stalled, but export would be unaffected.
E) Nothing would change; this is the normal Ran-GAP and Ran-GEF distribution.
