So first it's G-C-C. That's the green one. And then it's CCU, that's the orange one. The third sequence is C-U-U that's the purple one. And notice that these three codons, the green codon, the orange codon and the purple codon all have overlapping sections. And that's because in this case, the ribosome essentially moves one nucleotide over every time it reads that RNA chain. Now this is not how our ribosome reads it.
