So in this diagram, we move three nucleotides to the right. So this entire ribosome moves three nucleotide to the right, and that places our uncharged tRNA molecule, the tRNA molecule that does not contain the amino acid. So this tRNA molecule moves into the east side, which is this location here. So we move three nucleotides this way, this uncharged tRNA moves into the e side, and our charged tRNA that contains the growing polypeptide chain moves from the a side and into the p side as shown in the diagram. And now our a side shown here is empty. And once our a side is empty, what happens is this entire process can repeat itself.
