So once that molecule, the rRNA, binds onto the Shine Del Garner sequence, it forms that complex, it stimulates the tRNA to bring this form of methionine onto that Aug and that essentially establishes the reading frame of that mRNA molecule. Now, what do we mean by the reading frame or establishing the reading frame? Well, what that means is we essentially establish all the codon sequences that we're going to read on that mRNA molecule. So this becomes our first codon and this is essentially the methionine molecule. Then we have CUC, then we have UCC, then we have Ugg and so forth. And so once we know that this is our first codon, the next triplet nucleotide sequence is codon number two.
