Now, what exactly is the purpose of placing our uncharged tRNA into our easide? Well, the easide stands for the exit side. And once our uncharged tRNA molecule, the tRNA molecule that does not contain the amino acid, is moved into the east side, our ribosome then expels. It removes our tRNA from the east side of our ribosome. And this entire process, the process by which our ribosome actually slides along the mRNA and these tRNAs are expelled from the ribosome, is known as the process of translocation. Now, once the acide is empty, the process can repeat itself to add another amino acid.
