Our small subunit basically tells its signals a tRNA molecule to go out and find a methionine molecule and it brings our tRNA brings that methionine molecule to our aug. So this is our tRNA molecule. It contains the complementary sequence to our aug. So if this is the five end and this is the three end we have aug, then this is the three end UAC and this is the five end. And so once our small subune locates the start codon, this basically goes out and this goes out and finds our methionine which is shown in orange and then it brings our methionine to this location. And once our tRNA combines with this region, our large subunit also combines with a small subunit.
