During translocation in protein synthesis, the ribosome moves along the mRNA strand, allowing new tRNAs to enter the A site, while the tRNA in the P site is moved to the E site and then exits the ribosome. The tRNAs and the growing polypeptide chain do not move independently; they are moved as a result of the ribosome's movement.
