Figure 5From: The fundamental tradeoff in genomes and proteomes of prokaryotes established by the genetic code, codon entropy, and physics of nucleic acids and proteinsLimits of the codon entropy in genomes with the natural amino acid composition preserved. A, Natural nucleotide composition (black); synonymous codons substituted with the GC-richest ones (red) and the GC-poorest ones (green); synonymous codons were used uniformly (blue), GCNCB. B, Natural nucleotide composition (black); reduced synonymous codons (orange) – in cases when there are several synonymous codons with the same GC saturation, only one codon was used.Back to article page
