Sentence examples for ancestral usage from inspiring English sources

This was the deer chaser, an elegant water-fed device that, in its ancestral usage, was intended to scare the animals away from a garden's delectable moss.

Note that Kp/Ku is independent of ancestral codon usage bias, so that genes exhibiting either ancestrally high or low codon usage bias may both be expected to yield Kp/Ku ratios close to 1 if there is no change in selection for synonymous codon usage in any descendant lineages.

Modifications to the simple parsimony approach could also improve inference of ancestral codon usage.

These results suggest that ML generally allows more reliable inference of ancestral codon usage than MP for lineages within the D. melanogaster subgroup.

This study addresses the accuracy of ancestral codon usage inference using the phylogenetic relationships and distances among species in the Drosophila melanogaster subgroup as a model tree.

Here, we employ computer simulations to determine the reliability of ancestral codon usage inference under parsimony and likelihood approaches that have been employed in studies of Drosophila codon bias evolution.

Download software to infer ancestral amino acid usage for a set of protein sequences.

Using available data, we were able to unequivocally resolve the ancestral G-protein usage phenotypes for the ciliary, rhabdomeric and RGR/Go-coupled opsin clades (figure 6).

Therefore, an ancestral amino acid usage was determined separately by kingdoms as follows: Amino acids were first scored from 20 to 1 in terms of descending order of their frequencies in each designated species.

Phylogenetic analysis [ 22] suggests that species within the melanogaster and obscura groups show roughly the ancestral pattern of codon usage, while there has been a significant reduction in the usage of G- or C-ending codons in the common ancestor of the saltans and willistoni lineages.

The evolution of glutamine codon usage was estimated using ancestral state inference techniques.
