CodonExplorer: An online tool for analyzing codon usage and sequence composition, scaling from genes to genomes

Abstract

DNA composition in general, and codon usage in particular, is crucial for understanding gene function and evolution. CodonExplorer, available online at http://bmf.colorado.edu/codonexplorer/, is an online tool and interactive database that contains millions of genes, allowing rapid exploration of the factors governing gene and genome compositional evolution and exploiting GC content and codon usage frequency to identify genes with composition suggesting high levels of expression or horizontal transfer. © The Author 2009.
