Estimate Codon Usage Bias Using Codon Usage Analyzer (CUA)
2017One amino acid is added to a growing peptide by a ribosome through reading triple nucleotides, i.e., a codon, each time. Twenty species of amino acids are often coded by 61 codons, so one amino acid can be coded by more than one codon and the codons coding the same amino acid are called synonymous. Intriguingly, synonymous codons' usage is often uneven:

An Evaluation of Measures of Synonymous Codon Usage Bias
Journal of Molecular Evolution, 1998Synonymous codons are not generally used at equal frequencies, and this trend is observed for most genes and organisms. Several methods have been proposed and used to estimate the degree of the nonrandom use of the different synonymous codons. The estimates obtained by these methods, however, show different levels of both precision and dispersion when ...

Codon usage by chloroplast gene is bias in Hemiptelea davidii
Journal of Genetics, 2020The base composition of the chloroplast genes is of great interest because they play a highly significant role in the evolutionary development of the plants. Evaluation of the 48 chloroplast protein-coding genes of Hemiptelea davidii showed that the average GC content was about 37.32%, while at the third codon base position alone the average GC content

Codon usage bias in metagenomes
2008Codon usage (CU) bias is an effect predominant in prokaryotes whereby synonymous codons are used with different frequencies between different species and even between genes within a single genome. This effect is related to tRNA abundance and can be used to predict expressivity of proteins by comparing their CU with that of a reference set of ...

Nucleotide composition and codon usage bias of SRY gene
Andrologia, 2017The SRY gene is present within the sex-determining region of the Y chromosome which is responsible for maleness in mammals. The nonuniform usage of synonymous codons in the mRNA transcript for encoding a particular amino acid is the codon usage bias (CUB). Analysis of codon usage pattern is important to understand the genetic and molecular organisation

Selected codon usage bias in members of the class Mollicutes
Gene, 2011Mollicutes are parasitic microorganisms mainly characterized by small cell sizes, reduced genomes and great A and T mutational bias. We analyzed the codon usage patterns of the completely sequenced genomes of bacteria that belong to this class. We found that for many organisms not only mutational bias but also selection has a major effect on codon ...

Reduced Selection for Codon Usage Bias in Drosophila miranda
Journal of Molecular Evolution, 2007Biased codon usage in many species results from a balance among mutation, weak selection, and genetic drift. Here I show that selection to maintain biased codon usage is reduced in Drosophila miranda relative to its ancestor. Analyses of mutation patterns in noncoding DNA suggest that the extent of this reduction cannot be explained by changes in ...

Synonymous codon usage bias has been extensively studied in Bacteria and Eukaryotes and yet there has been little investigation in the third domain of life, the Archaea. In this thesis I therefore examine the coding sequences of nearly 70 species of Archaea to explore patterns of codon bias.
