Sentence examples for expression costs from inspiring English sources

While numerous studies have investigated regulation of expression level, little is known about gene design elements that govern expression costs.

The first one is that, under the specific conditions used in our experiments, insecticide resistance does not have any immune expression costs in field-caught mosquitoes.

Increasing concentrations of Pgal increase the growth rate, initially compensating for the protein expression costs, and eventually resulting in an overall growth rate increase of up to 1.6 doublings per hour.

Because many of these genes do not encode metabolic enzymes, it is not straightforward to predict the ensuing change in expression cost from a metabolic model.

However, since these isolates did not contain mutations in the promoter controlling lacZ expression, no cause for the observed loss of LacZ activity (which originated from selection against expression cost, not against activity) can be identified at present.

Reverses in the direction of the growth rate correlated transcriptional changes and the distinguished duties of the three clusters indicated how transcriptome homeostasis is maintained to balance the total expression cost for sustaining life in new habitats.

When the people are deprived of their basic rights and of their freedom of expression, it costs nothing to allow them to vent their anger, be it over Danish cartoons or the words of the Pontiff.

It's an unrehearsed encounter (though you can pre-plan what you would like to talk about), a form of expression that costs nothing to try, with everything to gain.

However, expression of costs and incomplete resistance sometimes changed markedly across different cultivars (Carrière et al. 2006).

A cost of resistance is fundamental for the theories of maintenance of genetic polymorphism (Boots and Bowers 1999; Best et al. 2008), but the expression of costs may be more labile than assumed by the models.

Consistent expression of costs on particular cultivars, the pervasive presence of toxic phytochemicals in cotton, and the possibility that increased penetration of phytochemicals may magnify costs in individuals with cadherin mutations, indicate that refuges could be manipulated over a large scale by planting specific cultivars to enhance resistance management in P. gossypiella.
