Codon Usage Bias Measured Through Entropy Approach
Codon usage bias measure is defined through the mutual entropy calculation of real codon frequency distribution against the quasi-equilibrium one. This latter is defined in three manners: (1) the frequency of synonymous codons is supposed to be equal (i.e., the arithmetic mean of their frequencies); (2) it coincides to the frequency distribution of triplets; and, finally, (3) the quasi-equilibr...
متن کاملMore Codon Usage Bias
χ measure. In statistics, the χ statstic computes how different the distribution of values is from a uniform distribution. Let d = c1 . . . cN be a DNA string in nucleotide alphabet, and let L be the total number of codons in d that are not Methinine or Tryptophan (the number does include the stop codons though). Let a be a k-degenerate amino acid, and let La be the total number of codons codin...
متن کاملSchistosoma mansoni: patterns of codon usage and bias.
Codon usage and bias has been examined in 20 genes of Schistosoma mansoni. Significant heterogeneity was detected in the patterns of codon usage and bias among genes by metric multidimensional scaling and three general indicators of bias (GC3S, Nc and B). In keeping with observations on sporozoan parasites, codon usage bias was observed to be dependent on the overall base composition of the gen...
متن کاملComparative Analysis of Codon Usage Bias Patterns in Microsporidian Genomes
The sub-3 Mbp genomes from microsporidian species of the Encephalitozoon genus are the smallest known among eukaryotes and paragons of genomic reduction and compaction in parasites. However, their diminutive stature is not characteristic of all Microsporidia, whose genome sizes vary by an order of magnitude. This large variability suggests that different evolutionary forces are applied on the g...
متن کاملMaximum likelihood estimation of ancestral codon usage bias parameters in Drosophila.
We present a likelihood method for estimating codon usage bias parameters along the lineages of a phylogeny. The method is an extension of the classical codon-based models used for estimating dN/dS ratios along the lineages of a phylogeny. However, we add one extra parameter for each lineage: the selection coefficient for optimal codon usage (S), allowing joint maximum likelihood estimation of ...
