Extensive C->U transition biases in the genomes of a wide range of mammalian RNA viruses; potential associations with transcriptional mutations, damage- or host-mediated editing of viral RNA

Frequency related transition asymmetries.
Transitional asymmetries of two virus datasets showing C->U/ G->A asymmetries. Normalised values (y-axis) were calculated for sites showing different levels of sequence heterogeneity (x-axis): 0.02: 0.02 or less; 0.05: <0.05 and ≥0.02; 0.1: <0.1 and ≥0.05; 0.25: <0.25 and ≥0.1; 0.4: <0.4 and ≥0.25; 1.00: ≥0.4.
