The phrase "at substitutions" is not correct and does not convey a clear meaning in written English.
It may be intended to refer to a specific context involving changes or replacements, but without additional context, it is unclear when to use it.
Example: "The results were analyzed at substitutions, but the data was inconclusive."
Alternatives: "during replacements" or "in the case of substitutions".
We counted AT to GC and GC to AT substitutions, omitting cases where the mutation occurred at a hypermutable CG dinucleotide.
Although there is a slight tendency toward evolving higher AT content in D. simulans, regions that possess higher GC ancestrally showed less accumulation of AT substitutions.
GC* was thus calculated on all non-CpG substitutions in each window according to the model of Sueoka (1962) as the percentage of AT → GC substitutions among all AT → GC and GC → AT substitutions.
However, not all GC → AT substitutions originate from post-mortem cytosine deamination and a number equivalent to the reciprocal class of substitution (namely, AT → GC) would be expected as a result of the process of lineage divergence.
The front-of-house team, mostly women from the town, scuttle about the brightly lit dining room inventing numbering systems for the larger tables and resisting any attempts at substitutions.
We have used the common analytical approach (based on synonymous codons alone) that looks at substitutions in the 3rd nucleotide position where most synonymous substitutions are found.
AT substitution attenuated thrombin generation significantly, as indicated by decreased concentrations of prothrombin fragments F1.2, thrombin antithrombin complexes and D-dimer at the end of surgery.
Pirkis said that studies which have looked at substitution suggest that although restricting access at one site could shift the problem in part to other locations, it still results in a significant overall reduction in deaths by the same method.
We look at substitution failures.
The few evaluations in developing countries corroborate the effects on employment but do not look at substitution and windfall effects.
Biobased elastomer materials from renewable resources aimed at substitution of petroleum-based derivates for engineering application have recently become a growing research focus.
