Sentence examples for basis of the codon from inspiring English sources
Bayesian assignment analysis, a method for dividing a collection of isolates into multiple genetic clusters on the basis of difference in allelic frequency at multiple marker loci was performed using BAPS ver. 5.2 [16] on the basis of the "Codon linkage model," employing the option of "clustering with linked loci".
For each pair of genes we compare the corresponding codon distributions on the basis of the codon frequencies in the two genes.
On the basis of the codon usage difference measure, Karlin et al. then derive the E(g) gene expression measure as: 3 where C represents the set of all protein-coding genes in the organism of interest.
Finally, we discuss a possible biochemical basis for the codon preferences we observe.
Attempts to detect the narB gene (coding for NR in other cyanobacteria) by PCR with primers designed on the basis of the specific codon usage in Prochlorococcus were unsuccessful.
The molecular basis of the AGN codon family with UCU-tRNASer can be interpreted by the high versatility of U in wobble-pairing.
Cases of sCJD were classified according to Parchi et al. that identified six molecular subtypes on the basis of the PRNP codon 129 polymorphism and PrPres type [7].
Four IFNB pairs out of 15 pairwise comparisons examined provide some evidence for purifying selection on the basis of the pairwise codon based Z-test (Table 6), but such selective pressures are not evident for the family as a whole (p = 0.171).
Synonymous mutation, the basis of the evolution of codon usage, are clearly the kind of "nearly neutral" mutations that likely play a large role in molecular evolution [ 57].
Besides other mechanisms, it is also suggested that codon bias can influence gene expression by optimization of the translational rate and thus, highly expressed genes can be characterized on the basis of biased codon usages compared with average genes.
Third, isolates were assigned to a principal genetic group on the basis of polymorphisms at codon 463 of the katG gene, which encodes catalase peroxidase, and at codon 95 of the gyrA gene, which encodes the A subunit of DNA gyrase (13 ).
