We identify a set of 575 human genes that are expressed in all conditions tested in a publicly
available database of microarray results. Based on this common occurrence, the set is …

The vast amount of data generated by genome projects and the recent development of
population genetics models make comparative sequence analyses a very powerful …

We measured the expression pattern and analyzed codon usage in 8,133, 1,550, and 2,917
genes, respectively, from Caenorhabditis elegans, Drosophila melanogaster, and …

Revealing the determinants of codon usage bias is central to the understanding of factors
governing viral evolution. Herein, we report the results of a survey of codon usage bias in a …

Transfer RNA (tRNA) gene content is a differentiating feature of genomes that contributes to
the efficiency of the translational apparatus, but the principles shaping tRNA gene copy …

Codon usage bias refers to the phenomenon where specific codons are used more often
than other synonymous codons during translation of genes, the extent of which varies within …

In many organisms, selection acts on synonymous codons to improve translation. However,
the precise basis of this selection remains unclear in the majority of species. Selection could …

Synonymous sites are generally assumed to be subject to weak selective constraint. For this
reason, they are often neglected as a possible source of important functional variation. We …

Three highly pathogenic human coronaviruses can cause severe acute respiratory
syndrome (SARS-CoV, SARS-CoV-2 and MERS-CoV). Although phylogenetic analyses …

The phenomenon of codon usage bias has been important in the study of evolution because
it provides examples of weak selection working at the molecular level. During the last two …
