Note to players: Description acceptable mRNP complexes become free from associated factors by Dbp5 helicases after this process is accomplished by NXF1 and NXT1. It’s neither transcription nor replication, but genetic analysis of mutant SV40 (“S-V-40”) viruses identified that one form of this process is necessitated by arginine/lysine-rich (“AR-juh-neen LIE-seen”) motifs. A complex involved in this process selectively regulates it using a disordered matrix abundant with FG repeats. Proteins destined for this process are “tagged” with (*) NES or NLS sequences. This process is cyclically mediated via the establishment of Ran-GDP and Ran-GTP concentration gradients. During this process, importins and exportins help macromolecules travel between a basket-shaped pore complex. For 10 points, name this process of moving cargo in and out of a chromosome-storing organelle. ■END■
ANSWER: nuclear transport [or nucleocytoplasmic transport; accept nuclear shuttling; accept nuclear import; accept nuclear export; accept nuclear localization; accept descriptions about transporting material in and out of the nucleus; prompt on cargo transport; prompt on diffusion]
