Fig. 1

Synonymous codon fraction versus GC content. Relative frequencies of stop (right panel), GC-rich (left panel), and AU-rich (middle panel) synonymous codons in gene categories with increasing GC content. Red circles indicate the fraction of AU-rich codon (UGU) of the 2-fold degenerated cysteine family (UGC and UGU). Blue symbols indicate the fraction of AU-rich codons (GCA and GCU) of the 4-fold degenerate alanine family (GCA, GCC, GCG and GCU). Values in the right panel represent mean ± SEM
