Transfer of MRNA from the Nucleus to the Cytosol Occurs

Question

Transfer of mRNA from the nucleus to the cytosol occurs through
A) carrier proteins.
B) gap junctions.
C) nucleosides.
D) gap lines.
E) nuclear pores.

Accepted Answer

Transfer of mRNA from the nucleus to the cytosol occurs through nuclear pores. Nuclear pores are large protein complexes that span the nuclear envelope, allowing selective transport of macromolecules between the nucleus and the cytosol. mRNA molecules are transported through the nuclear pores by binding to specific transport proteins called exportins.
