Sentence examples for unlinked copies from inspiring English sources

We generated strains with three tandem copies of TRP1 on a single plasmid (Clustered, Cls) or three unlinked copies (Dispersed, Dsp), and expressed Dicer without Argonaute to allow siRNA formation but minimize the effect of RNAi on total RNA levels.

The strong correlation observed among noncontiguous members of gene modules that are sometimes separated by more than 30 kb is consistent with vertical transmission but argues against horizontal transfer, which would require a simultaneous transfer of unlinked copies to all species, a highly unlikely event.

Multiple unlinked copies cause complex segregation patterns, potentially requiring screening over many generations to establish the zygosity of a line.

We assess the role of reticulation at both levels in the genus Elymus L. of the wheat tribe Triticeae (Poaceae), using phylogenetic analyses of three unlinked, low-copy genetic markers.

To differentiate between different causes of gene tree discordances, the use of multiple, potentially unlinked low-copy gene regions is desirable (e.g. [ 12- 15]).

All the teleost fish species that have an epd gene in the FishTj group also have an unlinked epd copy in the FishBrain group.

It is significant that three species of coryneform bacteria possess an unlinked second copy of trpD (denoted TrpD_r), which is a remnant of the native displaced operon that still persists in other actinomycete Bacteria.

A two-element Activator/Dissociation (Ac/ Ds) gene trap system was successfully established and used for insertional mutagenesis in maize and numerous heterologous species to generate collections of stable, unlinked, and single-copy Ds mutants.

The rRNA genes were found in single copies and unlinked; the 23S and the 5S are organized as an operon and the 16S rRNA is located 166 kb downstream of these genes.

This gene pair is present in multiple copies at unlinked loci in some Sordariomycetes; phylogenetic analysis suggests that lineage duplication events resulted in these extra copies.

In contrast, segmental and ectopic duplications, which involve the duplication of entire gene blocks or single/small groups of genes respectively, can position copies to unlinked sites including different chromosomes [ 51].
