Figure 1From: Ambushing the ambush hypothesis: predicting and evaluating off-frame codon frequencies in Prokaryotic GenomesExample of OSC formation. There are six ways in which an arginine AGT codon at position i can form OSCs with codons at position i-1 or i+1. OSCs are given in upper case and red. X represents any base for the codons in positions i-1 and i+1.Back to article page
