Correlation of oligonucleotide frequencies between virus genome and exon region of host animals. A, B Venn diagram showing di-, tri-, and tetra-nucleotides that were specifically high in frequency in host animals. The oligonucleotides that are (A) more or (B) less frequent in the human exon region than the exon region in each bat. The notation in the Venn diagram is as follows. MOL: Molossus molossus, MYO: Myotis myotis, PHY: Phyllostomus discolor, PIP: Pipistrellus kuhlii, RHI: Rhinolophus ferrumequinum, ROU: Rousettus aegyptiacus. C, D Venn diagram showing di-, tri-, and tetra-nucleotides that were specifically high in frequency in human-CoV and the human genome and in Bat-CoV and the bat genome, respectively
