Each of these enzymes and transporter genes is known to exhibit a degree of genetic variation, characterised by single nucleotide polymorphisms (SNPs) (Ingelman-Sundberg et al, 1999; Ariyoshi et al, 2001; Kim et al, 2001; Lal et al, 2007).
The high levels of variation characterising the mitochondrial DNA (mtDNA) molecule are due ultimately to its high average mutation rate; moreover, mtDNA variation is deeply structured in different populations and ethnic groups.
All qRT-PCR assays are characterised by biological variation, mainly the inherent variability of mRNA levels in different tissues and individuals, but also analytical variations characterised by differences in RNA quality, variability in extraction protocols, RT and PCR efficiencies that can lead to erroneous and confusing results (Huggett et al, 2005).
Overall, WOF, cooking temperature and genotype were differentiated as individual dimensions through sensory profiling of the meat samples and each source of variation was characterised by specific groups of sensory descriptors.
The solid products of 11 starting mixtures of oxide/carbon variations were characterised ex situ by chemical, phase, and morphological analyses.
This demonstrates the variability of SVA insertions between individuals; our study extends the analysis of their polymorphic nature to include the variation found in the CCCTCT hexamer repeat and provides further evidence of the already characterised variation in the second domain of the central VNTR (Table 2).
They characterised patterns of genetic variation for salivary amylase, the enzyme responsible for starch digestion in humans.
Rearrangements of the cancer genome, including amplifications/deletions and chromosomal translocations, represent a biologically and clinically important, but poorly characterised, class of somatic variation in cancer.
Indeed, most attempts to investigate intrahost genetic variation in DENV characterised only a few viral genes or a limited number of full-length genomes.
Given the variations that characterise our weather systems, a period in which the rate of warming slowed is not unexpected.
