Sentence examples for models of substitution from inspiring English sources
Pilot studies of available alignments of orthologous coding sequences47 showed congruence in relative ΔSSLS estimates for each locus under different models of substitution (available on request).
Moreover, codon models of substitution rates and models evaluating the magnitude of change to physical amino acid properties demonstrate little evidence for adaptive evolution and suggest that elevated nonsynonymous substitution rates in these domains represent relaxed selective constraint.
We explored the effect of a variety of substitution and recombination rates, sequence lengths, numbers of taxa, and models of substitution on the relative accuracy of these network and standard phylogenetic approaches.
Mixed models of substitution, in which a matrix describes the changes among nucleotide pairs and another matrix is fitted for single nucleotide changes, thus potentially provide a better fit to nucleotide sequence data from such molecules [12], [37], [45], [65].
In molecules constrained by secondary structure such as 18S and 28S rRNA, the nucleotides involved in stems and loops do not evolve independently, as assumed with standard models of substitution [62], [63] such as those compared in Modeltest [64] and jModelTest [56].
Three models of substitution are analyzed.
A priori knowledge about physical or chemical properties of nucleotide or amino acid residues can be used to define mechanistic models of substitutions.
Similar estimates of branch lengths were obtained for different models of substitutions (Table S4) suggesting that the obtained results are reliable.
