Evolution of synonymous codon usage in metazoans.
The vast amount of data generated by genome projects and the recent development of population genetics models make comparative sequence analyses a very powerful approach with which to detect the footprints of selection. Studies on synonymous codon usage show that traits with minuscule phenotypic effects can be molded by natural selection. But variations in mutation patterns and processes of bia...
متن کاملMutational Pressure Drives Evolution of Synonymous Codon Usage in Genetically Distinct Oenothera plastomes
Background: Most of the amino acids are encoded by more than one codon, termed as synonymous codons. Synonymous codon usage is not random as it is unique to species. In each amino acid family, some synonymous codons are preferred and this is referred to as synonymous codon usage bias (SCUB). Trends associated with evolution of SCUB and factors influencing its diversification in plastomes of gen...
متن کاملSynonymous Codon Usage Controls Various Molecular Aspects
Synonymous sites are generally considered to be functionally neutral. However, there are recent contradictory findings suggesting that synonymous alleles might have functional roles in various molecular aspects. For instance, a recent study demonstrated that synonymous single nucleotide polymorphisms have a similar effect size as nonsynonymous single nucleotide polymorphisms in human disease as...
متن کاملSynonymous codon usage in bacteria.
In most bacteria, synonymous codons are not used with equal frequencies. Different factors have been proposed to contribute to codon usage preference, including translational selection, GC composition, strand-specific mutational bias, amino acid conservation, protein hydropathy, transcriptional selection and even RNA stability. The review discusses these factors and their contribution to bias i...
متن کاملIdentification of Synonymous Codon Usage Bias in the Pseudorabies Virus UL31 Gene
Background: Little knowledge of synonymous codon usage pattern of pseudorabies virus (PRV) genome, especially the UL31 gene in the process for its evolution is available. Objectives: In the present study, the codon usage bias between PRV UL31 sequence and the UL31-like sequences was identified. Materials and Methods: We used a comprehensive analysi...
