Compositional biases human mRNA vs (+)SARS‐CoV‐2.
The histogram of the compositional difference between Homo sapiens mRNAs and the SARS‐CoV‐2 genome shows a considerable counterselection for the presence of cytosine (and guanine) nucleotides. The figure plots the log2[v(i)/h(i)] ratio of the content in the virus over the content in human cytoplasmic mRNAs.
