Sentence examples for substitution category from inspiring English sources

A site need not contribute an integer count of 1 to a single substitution category, but fractional counts summing to 1 can be spread out over all 16 categories.

Finally, for the 1st and 2nd codon positions we used the model with only one substitution category with all rates equal (F81 model), and for the 3rd codon position we used the model with 6 categories with a gamma shape parameter plus invariants including the covarion parameter (GTR+Γ+I+cov model).

Therefore, differences appeared when the individual substitution categories were probed.

Neighbouring patterns differed both among substitution categories and within a category that occurred at three codon positions.

On the other hand, the categories for substitutions were spread far apart along both dimensions, indicating that substitution categories were well discriminated in both dimensions.

We used PHYML to estimate the proportion of invariable sites and the gamma distribution parameter (with eight substitution categories).

There are 12 substitution categories, i.e., each type of nucleotide can change into any of the other three types.

Substitution categories (silent, non-silent (missense and nonsense), non-coding (tRNA and rRNA), and intergenic) are shown by the shapes of each substitution.

The use of immediately adjacent nucleotides revealed differences both among substitution categories and within a category that occurred at three codon positions.

The periodic patterns of flanking nucleotides varied both among substitution categories and within a category that occurred at three codon positions.

The HKY + I + G model with 6 substitution categories was determined to be the most suitable model by Modeltest and was used for all subsequent nucleotide analyses.
