Nuclear pores primarily function in:
Show answer and explanation
Correct answer: Selective bidirectional transport between nucleus and cytoplasm
Nuclear pore complexes regulate the bidirectional exchange of macromolecules between the nucleus and cytoplasm. RNA molecules (mRNA, rRNA, tRNA) are exported outward while proteins, such as transcription factors and histones, are imported inward. This selective transport is energy-dependent and mediated by importins and exportins.
