Sentence examples for low sequence variability from inspiring English sources

Many potential markers are inappropriate for certain applications due to low sequence variability (e.g., rpoB, ndhJ, accD, atpB, COX1, 5.8S rRNA) [ 21].

However, due to the low sequence variability, haplotype network was not informative on R. acetosa, while for C. communis populations some clustering of haplotypes was recognized.

They included Peabody, which made up 2 3% of the genome and displayed very low sequence variability suggesting its recent amplification.

However, despite their short length and low sequence variability, the rRNA genes of Nosema/Vairimorpha vary exceptionally in the order in which they occur within the ribosomal repeat unit.

Characteristic low sequence variability of satDNAs is considered to be a consequence of a phenomenon called concerted evolution, in which mutations are homogenized among repeats of a family in a genome and fixed among individuals in a population (Dover 1986).

Although the signal peptide and pro-peptide regions show low sequence variability, the C-terminal region of MgCRP-I corresponding to the putative mature peptide appears hypervariable (fig. 1).

Genes with the lowest sequence variability (per unit length) include cox1 (0.296), cox2 (0.323) and rrnS (0.330).

Such a cis-regulatory role would fit with the low TE and the high sequence variability (low phastCons scores) observed for uORFs.

Since, as recently shown by computer simulations [31], recombination can act as a homogenizing mechanism by the random exchange of short DNA sequences, the higher value of ρ in this region could contribute to explain the remarkably low level of sequence variability of rrgC compared to the other two structural components rrgA and rrgB (see Table 1).

Among the 21 probes, 2 probes are shared by more than one species due to low or absence of sequence variability, i.e. Rpam for Rhizopus azygosporus/Rhizopus microsporus and Fumop for Fusarium moniliforme/Fusarium oxysporum/Fusarium pallidoroseum.

For land plants, the coxI gene, and the mitochondrial genome in general, is not useful for identification at the species level because of low levels of primary sequence variability [18], [19].
