Abstract We have investigated the genome organization in the flatworm Schistosoma mansoni. First, we analyzed the compositional distributions of the three codon positions. Second, we investigated the correlations that exist between (1) the GC levels of exons against flanking regions, (2) the GC levels of third codon positions against flanking regions, (3) the dinucleotide frequencies of exons against flanking regions, and (4) the GC levels of 5′ against 3′ regions. The modality of the distribution of third codon positions, together with the significant correlations found, leads us to propose that the nuclear genome of this species is compositionally compartmentalized.
