Figure 3From: Pandemic influenza A virus codon usage revisited: biases, adaptation and implications for vaccine strain developmentCodon usage of H1N1 pdm IAV plotted against the codon usage of human cells. Colors reflect the nucleotide that occupies the first anticodon position (wobble position) of the corresponding codon. A, C, G and T are indicated by red, blue, green and black diamonds, respectively.Back to article page
