Sentence examples for mutation pressure on from inspiring English sources

It would suppress the malaria-susceptible mosquitoes without creating mutation pressure on all mosquitoes to evolve a fungus-resistant form, as DDT created pressure to evolve pesticide-resistant forms.

The effect of asymmetric mutation pressure on the amino-acid composition of proteins has been reported elsewhere [ 40- 42].

Directional mutation pressure on each strand of DNA and translational selection are major factors in codon usage bias [ 59].

Furthermore, we also examined the influence of mutation pressure on MARV codon usage via correlation and linear regression analyses between different nucleotide compositional constraints, ENC, and principal axes.

This would imply that mutation pressure on total fitness could be much greater than studies examining juvenile fitness alone would imply.

It has been noted that orthologs on the leading strands show lower rates of divergence than those on the lagging strands among various bacteria; this is a reflection of lower mutation pressure on the leading strand [ 28].

Such rate variation is mostly likely attributed to differences of selection intensity rather than differential mutation pressures on the genes.

Consequently, differences of selection intensity are most likely to account for the substitution rate variation in the GA pathway genes, though differential mutation pressures on genes cannot be excluded entirely.

Based on sequence analyses of 7 core structural genes of the gibberellin biosynthetic pathway, we have detected significant rate heterogeneity among these genes for both synonymous and nonsynonymous sites and ascribed such rate variation to differences of selection intensity rather than differential mutation pressures on the genes.

Currently, we sought to evaluate mutation pressure acting on the entire prokaryotic genome by examining how the average GC3 content, calculated across all genes in a genome, is related to the position of the genome in a global ordering.

It has been postulated that the ENC-plot of genes for which codon choice is constrained only by compositional constraints or mutation pressure will lie on the continuous curve of the predicted ENC values [ 32].
