The patterns in nucleotide sequences are biologically functional only in conjunction with the organization (e.g., consider the function of a regulatory gene).
The e y 2 retrogene in Drosophila melanogaster performs a general function and is ubiquitously expressed, while the source gene e y 2b is functional only in a small group of male germ cells [ 16].
MAMMALS are named after their defining characteristic, the glands capable of sustaining a life for years after birth — glands that are functional only in the female.
Perhaps the best way to insult an American with aspirations to cosmopolitanism is to call him and his fellows ignorant rustics, functional only in English and kept safely away from real intellectual rigor and debate by geographical isolation, local peace, and relative material abundance.
But the American military organisation is truly functional only in the environment for which it was designed: combat.Thankfully, today's corporations don't face the prospect of losing a portion of their workforce or leadership during the morning commute.
In contrast, composite AuxRE is functional only in modular form with CG-rich 'coupling' or 'constitutive' element (Table 2).
Although both were functional, only the longest promoter sequence (PHev2.1) conferred a high level of expression to the transgene in various tissues of this heterologous host.
Yet, in both species nitrogen fixation occurred (heterocytes were functional) only when nitrogen was limiting, and nitrogen fixation increased significantly at higher phosphorus concentration.
Traditional pulsating heat pipe with fewer turns is functional only when the heat source is placed at the bottom while the heat sink is on top.
Moreover, the genomes of such alphaviruses can be engineered to contain RNA elements that would be functional only in cells of vertebrate, but not insect, origin.
"Application development gets so cheap that it makes sense to create something that is functional only to a small group of people, even for a limited time period".
