Low frequency of isolated (non-repeated) codons in C. albicans. Since codon repeats were very frequent in C. albicans and also in the other species we have computed separated the proportion of codons that appeared isolated or in identical codon-pairs, -triplets or longer strings. C. albicans had lower frequency of isolated codons (non-repeated identical codons) than the other species, although there was general repression of isolated codons in all species (panel A). This bias was reversed for repetitions of 2 or more identical codons, which again was exacerbated in C. albicans (red bar; panels B-D).
