How does an mRNA strand reach the site for Translation? A. It moves across the membrane through Active Transport
B. It exits the Nucleus through a Nuclear Pore
C. It is already where it needs to be, Translation occurs as soon as the mRNA is processed
D. A tRNA molecule carries it to the Ribosome

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.
