Sentence examples for based only on nucleotide from inspiring English sources
Based only on nucleotide substitutions (i.e., only 65 out of 218 substitutions were parsimony-informative in the olive tree complex), phylogenetic relationships were depicted from the complete cpDNA genomes using both maximum parsimony (MP) and maximum likelihood (ML) techniques.
Additionally, these estimates are based only on single nucleotide polymorphisms (SNPs); they do not include insertion and deletion differences.
However, these studies were typically based only on one or two thousand nucleotide characters or from a small number of genetic markers and therefore, each tree typically had low bootstrapping values or resulted in variations to this tree when differing methods or maternally, paternally or bi-parentally inherited data are used, suggesting that some of these relationships are still contentious.
For this calculation, gaps were treated as missing data, so the differences between sequences were based only on point mutations (nucleotide substitutions).
We computed the weighted percent GC based only on non-coding nucleotides of the compositional domains, because we did not wish to include effects of codon bias.
Based on the example given in this study, it may be interesting to develop rules and parameters to assign EST sequences as miRNA precursors based only upon extensive nucleotide identity with precursors from highly closely related species.
This rate was calibrated based on a biogeographic split of only 0.1 Ma after which only one nucleotide substitution occurred [ 25].
Therefore we disregarded indels, and redistributed the reads to other clusters based on nucleotide polymorphisms only.
All calculations were based on nucleotide substitutions only (indels not included), as RIs of all data sets revealed this to be less homoplastic than the data sets containing indels (Table 1).
In Arabidopsis ~27000 genes were predicted based on nucleotide sequence information; however, only half of these genes have been functionally annotated based on sequence similarity to known genes, and among these the function of only ~11% has been confirmed with direct experimental evidence [ 60].
