The phrase "a fixed copy" is correct and usable in written English.
It can be used to refer to a version of a document or file that is unchangeable or has been finalized.
Example: "Please ensure that you send me a fixed copy of the report for our records."
Alternatives: "final version" or "static copy".
This removes the significant overhead of constructing a stable cell line with fixed copy number for each construct; hence, it facilitates large-scale investigations of transcriptional output.
Furthermore, the square-root and proportional replication schemes provide higher query success ratio than the fixed copy approach with varying node density.
This approach could be more robust than testing RNA and should enable the quantification of cells due to the fixed copy number of these sequences.
Two reference DNA samples (MRC5 and KE27) were used to construct standard curves of amplifications using GAPDH (fixed copy number reference gene) and telomere primer pairs; 1.68-fold serial dilutions were made for each DNA covering a range of 7.4 0.93 ng/μl.
However, segregating and fixed copies are lost at different rates too.
This DNA turnover phenomenon that appears to fix copy variants within interbreeding populations provides a complementary tool for identifying genetic discontinuities and species boundaries.
To explain what he means by the "social life" of information, Mr. Brown points to a Xerox project to build a database of information about fixing copying machines.
It is shown that the operators not fixing copies of l1 on a Daugavet pair satisfy (1).
To normalize these counts for all three large repeats, a more stringent count was also taken, which required that read pairs map in a fixed window around each repeat copy (from 15 kb to 35 kb to either side of the repeat midpoint).
