Sentence examples for variations at single from inspiring English sources

Importantly, quantitating variations at single sites is not always possible and 30% of detected peptides carry multiple phosphorylations, 5a for which measuring contribution of each site to the total variation of phosphopeptide may not be feasible.

Few previous studies have employed such large collections of intraspecific sequence variants in order to analyze patterns of adaptive molecular variation at single genes [22].

Next-generation sequencing technologies now present the possibility of determining genome-wide genetic variation at single base-pair resolution.

Variations observed at single cell level indicated insufficient M2-transactivator levels for a subset of the transduced cells.

Single nucleotide polymorphisms (SNPs) are variations at a single base pair (fig 1 ) and are the most common type of human sequence variation, occurring about every 500-1000 DNA base pairs.

Some of them are mutations located within endonuclease restriction sites, others are single nucleotide polymorphisms (SNPs: DNA variations at a single nucleotide) or consist of insertions or deletions of larger fragments as detected by polymerase chain reaction technique (PCR) [ 9].

To date, surveys of mitochondrial coding regions in corals [ 25, 27, 28] have found little or no variation, but these studies have included just a few individuals (≤ 8) and a few localities (≤ 3), and have not been accompanied by surveys of variation at single-copy nuclear markers.

It has now become more common in molecular genetic studies to perform association analysis covering the whole genome by considering associations with a large array of single nucleotide polymorphisms (SNPs) (i.e., variations at a single nucleotide site that differ between members of a species; McCarthy et al. 2008).

Interphase FISH technique is known as a powerful approach to assess intercellular chromosome variations at the single cell level [3], [4].

Such analysis would allow us to capture spatial variations at a single time stage, as well as varying relationships between genes across time.

We analyzed spatial genetic variation in wild barley populations collected rather recently, exploring sequence variations at seven single-copy nuclear loci, and inferred the relationships among these populations and toward the genepool of the crop.
