Sentence examples for level of tandem from inspiring English sources

This is consistent with observations for Arabidopsis, where the level of tandem gene duplication in the germin family is more than two standard deviations above the genome median (Cannon et al. 2004).

An unusual aspect of all published Xist RNAs is their high level of tandem repeats, some of which have been shown to be functionally important, possibly working in a cooperative fashion [9].

Teleost fish genomes are well known for their whole genome duplication events, and high level of tandem and segmental gene duplications had been observed in teleost species.

Two families in which the level of tandem duplication is more than two standard deviations above the genome median are the germin and major latex protein (MLP) families.

A lower level of tandem gene duplication events (at least in the MST gene family) may also be a factor in the low number of expressed MST loci.

In addition, there is increasing evidence for high level of tandem and interchromosomal duplication events in wheat and perhaps barley genomes since their divergence from the other grasses [ 16, 39].

Counts of tandem and segmental duplications were negatively correlated; no families exhibited both high levels of tandem and segmental duplication.

Recent genome sequencing projects have revealed that the water flea, Daphnia pulex, and the pea aphid, Acyrthosiphon pisum, are unique among arthropods in having exceptionally high levels of tandem, lineage-specific gene duplication and retention [ 2- 9].

Although the distribution of gene family sizes across the genome can be accounted for by a stochastic model, by comparing the relative levels of tandem and segmental duplication in large gene families, we can speculate that gene function might feedback on copy number and genome organization, and thus result in the widely varying patterns of observed tandem and segmental duplication.

Comparing the levels of overlapping (tandem) and non-overlapping (competitive) A5Es and A3Es, a clear preference of isoforms was seen for tandem acceptors and donors, with four nucleotides and three to six nucleotides long exon extensions, respectively.

We observed a moderate negative correlation between levels of predicted tandem and segmental duplications in gene families.
