Sentence examples for calculation of the evolutionary from inspiring English sources

Sucess in the effort to clone DNA from the mammoth would make possible a close calculation of the evolutionary distance between these great animals, which became exinct about 10,000 years ago; and the two living species of modern elephants.

Previous calculation of the evolutionary rate of HRSV has been undertaken by analysing G gene sequence data, with rates of 1.83×10−3 and 1.95×10−3 substitutions/site/year determined for subtypes A and B respectively [10], [11].

Calculation of the pairwise evolutionary distances between species was done for each one of the sequences (intron, enhancer an proximal promoter) by means of the Tajima-Nei method [ 44] using MEGA 3.1 program [ 45].

Calculation of the co-evolutionary risks of altered antigen-specificity of immune responses is therefore essential; might cross-reactive vaccines impose strong selection for escape mutants to make larger antigenic, and perhaps more virulent, leaps than they do naturally?

Both the calculations of the molecular evolutionary rate and of the phylogenetic informativeness profiles were performed using the PhyDesign web application [ 27].

Calculations for the dating of the evolutionary events were carried out using a synonymous mutation rate of 1.4 × 10-8 substitutions per synonymous site per year, which was established for the CHALCONE SYNTHASE gene in eudicots [ 63].

Those pairs that satisfy a divergence threshold (defined as the fraction of the alignment total length) are used for the calculation of evolutionary distances.

On the basis of pairwise distance calculations alone, the evolutionary divergence between C. paramecium and G. theta/ R. salina was invariably greater than between G. theta and R. salina (supplementary table S1, Supplementary Material online).

If one is to consider the quality of each of the types of data involved in calculation of the partial correlations – expression data, evolutionary rate data, and interaction data – there is no question that the least reliable of the three are the interaction data.

The calculation of evolutionary distance among chicken chromosome 1, zebra finch chromosome 3, and GRC sequences confirmed the closer relationship of GRC sequence to zebra finch chromosome 3 than to chicken chromosome 1 (Fig.  8c, d).

The calculation of evolutionary distances for plant SDHs revealed a pair-wise distance under 0.3 in general (Additional file 2: Table S2), sequence alignment showed that Class I SDHs tend to be more conserved (average sequence pair-wise identity 83.4%; Table  1) than Class II (79%; Table  1), which means less amino acid substitution within the Class I clade.
