The strand of mRNA passes from the A to the P sites of the ribosome before exiting at the E site. At the A site, tRNA molecules connect to the codons of mRNA before moving to the P site, where their amino acid is added to the growing polypeptide chain.

The correct answer is B: it exits the nucleus through a nuclear pore.
