Fig. 2From: Genomic analysis of codon usage shows influence of mutation pressure, natural selection, and host features on Marburg virus evolutionParity Rule 2 (PR2)-bias plot [A3/(A3 + U3) against G3/(G3+ C3)]. PR2 biasness plot is calculated for whole genome and individual MARVs genes which are indicated by “All” and one letter codes respectively.
