And we'll see that there are two other important sites that exist inside our ribosome known as the a side as well as our e site. So we see that the process of translation involves three types of RNA molecules. We have mRNA, tRNA and rRNA. And basically what happens during the first stage of translation is our mRNA locates our small subunit which then basically finds our aug star codon sequence. And once it finds, it signals Atrna to pick up the methionine amino acid and bring it into our small subunit. And once that bi takes place, it signals the large subunits shown here.
