Example sentences for: single-copy
How can you use “single-copy” in a sentence? Here are some example sentences to help you improve your vocabulary:
Since the basic single-copy repertoire of dispersed aromatic-pathway genes shown in Figure 2for Synechocystis (Ssp) is representative of other cyanobacteria such as Synechococcus (Syn) and Prochlorococcus (Pmu) and is also present at dispersed extra-operonic loci of Anabaena and Nostoc , an obvious possibility would seem to be that the genes of the supraoperon originated by LGT in a common ancestor of Anabaena and Nostoc . If so, speciation was followed by different species-specific gene-insertion events.
These repeats are often part of the trans-silencer locus or paramutagenic locus or its target [ 10 14 15 16 17 ] . However, the repeat can sometimes be located at a considerable distance from the affected locus itself, as has recently been shown for the single-copy maize b1 gene [ 18 ] . Other than transcriptional gene silencing, paramutation is only weakly correlated with DNA methylation.
The problem of random transgene integration can be overcome by targeting transgenes to a specific genomic locus by homologous recombination in ES cells [ 2 3 4 ] . A method that allows the introduction of single copy transgenes into the X-linked hprt locus has been described previously by Bronson et al [ 2 ] . In this approach single-copy transgenes are introduced 5' of the hprt locus by homologous recombination in ES cells.
It contains tandemly repeated short sequences (satellite DNAs), middle repetitive elements (for example, transposable elements), and some single-copy sequences [ 4].
Sinorhizobium meliloti , for example, has three large, single-copy plasmids [ 43 ] , and the primary Mesorhizobium loti chromosome is linear.
