In this particular case, as the ribosome reads our codons, there is overlap between the codons. But in this case there is no overlap. And it turns out that this is how the ribosome actually reads that sequence of nucleotides. So we have the sequence of nucleotides, this is the five prime and this is the three prime. And we have twelve nucleotides as shown. Now, when the ribosome reads our nucleotide sequence, it reads it via these codons.
