The phrase "active copy" is correct and usable in written English.
It can be used in contexts related to marketing, advertising, or content creation, referring to text that is currently being used or is effective in engaging an audience.
Example: "The active copy on our website has significantly increased our conversion rates over the past month."
Alternatives: "current text" or "engaging content".
Together, these findings suggest that both SR3-left and SR3-right are full-length copies and, moreover, that SR3-right is an intact, putatively functional and active copy, capable of autonomous retrotransposition activity.
Scientists supported by the Geron Corporation of Menlo Park, Calif., discovered recently that human cells grown in glassware could be made to divide indefinitely -- becoming in principle immortal -- if given an active copy of the telomerase gene that builds their telomeres back to youthful length.
Active Copy enables users to backup folders on their computer to a Pogoplug connected drive.
The body needs only one active copy of the X chromosome, so in females, the second copy is disabled.
Removing the insertion element (and thereby restoring an active copy of comP) resulted in reduced genetic competence (Hoffmann et al. 2010), which clearly differs from B. subtilis.
Now users can also use Active Copy to automatically backup key files from one Pogoplug to another off-site Pogoplug, for additional safety and redundancy.
The genome of the green anole continues to sustain strong transposition activity while there are almost no active copies in the alligator anymore.
In the latter genome, transpositional activity from LTR retrotransposons has been shown to be decreasing over time but active copies are nevertheless still detectable.
For example, Alu has about 50,000 active copies while LINE-1 (long interspersed element 1) has approximately 100 active copies per genome.
For instance, Tonegawa says, researchers might be able to develop a drug that stimulates Bcl-2 production or a gene therapy that provides extra, active copies of the Bcl-2 gene.
It has been proposed that defective I elements act as the genetic determinants of reactivity and, through their differential expression, can modulate transposition of active copies [6], [7].
