Sentence examples for adaptive sequence from inspiring English sources
Positive selection, or adaptive sequence evolution, is the hallmark of evolutionary change and molecular adaptation.
This understanding of the construct is based on the assumption that problem solvers need to perform an adaptive sequence of cognitive steps in order to solve a specific problem (Jonassen [2011]).
We also tested for adaptive sequence evolution along the IIS pathway in these species.
Adaptive sequence evolution along the IIS pathway was studied in C. elegans, C. briggsae and C. remanei.
In line with this, we show that the components of this pathway do not show evidence of adaptive sequence evolution during the diversification of these species whereas the complement of putative downstream targets controlled by DAF-16 appear to vary between these species.
For each gene of interest, the presence of adaptive sequence evolution (ratio between synonymous [KS] and non-synonymous [KA] substitutions) was calculated between a pair of sequences (C. elegans and C. brigssae; C. elegans and C. remanei; C. briggsae and C. remanei) using PAL2NAL [57].
Within any one panel, the modules typically have two or more difficulty levels and, hence, permit adaptive sequencing for test administration.
CRISPR genes have been found in many bacteria and provide them with adaptive sequence-specific nucleic acid restriction mechanisms that act as a defense against invading mobile genetic elements such as bacteriophages, invading plasmids, and transposons [ 28– 33].
Therefore, our future work is to find the method to choose a self-adaptive sequence ({ {rho_{n} } }).
The relatedness of the two species means that any non-adaptive sequence differences are likely to be minimal, allowing the easier detection of pressure-adapted variations.
An analysis of polymorphism data on a set of genes from D. pseudoobscura that evolve rapidly with respect to their protein sequences revealed no evidence for a faster-X effect with respect to adaptive protein sequence evolution; their rapid evolution is instead largely attributable to lower selective constraints.
