We believe that the combination of being a versatile, designable, and now broadly characterizable regulator of gene expression places RNA in a unique and central position as a master substrate for engineering gene expression.
Whether gene expression places significant demands on the energy budgets of multicellular organisms is less explored [ 12, 16], but the widespread observation of weak selection on codon and amino acid usage suggests that even small differences in the efficiency of molecular processes can influence fitness and therefore have consequences for molecular evolution [ 17, 18].
Though the term itself is by no means inaccurate - the musicians described did produce just that one song that has been remembered by posterity - those who use the expression place far too much emphasis on the "one-hit" element and not enough on the "wonder".
This gene had been associated with the development of the diencephalon but lineage tracing and gene expression place it within the NMp population (Zhao et al., 2007).
In the pancreas of Th − / − embryos, in contrast with Th +/+ mice, the decrease in NGN3 expression was accompanied by an increase in Hes1 expression, placing the catecholamine effect, at least in part, at the level of Notch signalling regulation.
One clear interpretation of these patterns is that high levels of protein expression place a high demand for N upon somatic cells, creating a selection pressure for conservation of N in the most highly expressed proteins [ 4].
Its richness and power of expression place it in the knowledge spectrum to the left side of formal specifications but to the right side of rich descriptions consisting of images, sounds, video-clips and simulations of reality.
To perform this experimental activity, we have followed a cognitive theory-based approach, since the understanding of the cognitive demands that OCL expressions place on software engineers will allow us to examine in greater depth the real influence of import-coupling on the maintainability of OCL expressions.
It offers a genuine sense of the latitude of free expression and places a small, incisive shock in the midst of all those SoHo apparel shops and restaurants.
There are currently 17 other states that have statewide laws protecting on the basis of gender identity and expression, including places like Illinois, Iowa and Nevada.
Since definitions add new expressions to the object language, they add expressions in places where they can be quantified, and so can enhance the system's expressive power.
