Dinucleotide biases in the platyhelminth Schistosoma mansoni.
The analysis of dinucleotide biases in coding and flanking regions, introns, rDNA and repetitive sequences, in the flatworm Schistosoma mansoni is reported. Except for rDNA, all regions display CpG avoidance and TpG plus CpA excess, which might be evidence of the presence of 5mC. The distribution and hierarchies of dinucleotides differ from the data published for invertebrate and vertebrate coding sequences.
