Figure 1From: Variation in global codon usage bias among prokaryotic organisms is associated with their lifestylesProkaryotes showing extreme GC content have relatively high CAI ave values spanning a narrower range. Scatter plot of GC content (x-axis) and CAIave (y-axis) of 773 organisms. Here and in all other figures CAIave is indicated as 'Average CAI'. CAI: Codon Adaptation Index; GC: genome content.Back to article page
