The phenomenon of codon usage bias is known to exist in many genomes and it is mainly determined by mutation and selection to understand the patterns of codon usage in nemertean mitochondrial genomes, we use bioinformatic approaches to analyze the protein-coding sequences of eight nemertean species. Results here we show that differential nitrogen availability, due to differences in environment and dietary inputs, is a major determinant of genome nucleotide composition and synonymous codon use in both bacterial and eukaryotic microorganisms. Codon usage bias refers to differences in the frequency of occurrence of synonymous codons in coding dna a codon is a series of three nucleotides (a triplet) that encodes a specific amino acid residue in a polypeptide chain or for the termination of translation (stop codons).

Analysis of codon usage and nucleotide composition bias in were investigated and a comparative analysis of codon usage phenomenon, it is well known that . 26 sentence examples: 1 whether only the codon 129 genotype contributes to the molecular basis of this anticipation phenomenon is still unknown 2 the termination codon is denoted by a full stop. Genetic drift [2,3] therefore, understanding the codon usage bias can show the codon usage pattern of species, and provide evidence about the evolution of organisms many previous studies suggest that there are various fac-tors related to scub, determined by mutational bias alone or by both mutation bias and natural selection .
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 and among species. In a wide variety of organisms, synonymous codons are used with different frequencies, a phenomenon known as codon bias population genetic studies have shown that synonymous sites are under weak selection and that codon bias is maintained by a balance between selection, mutation, and genetic drift.
