While functional elements are subject to stabilizing selection, the adjacent non-functional DNA evolves much faster.
The regionally restricted enrichment of the class I alcohol dehydrogenase sequence polymorphism (ADH1BArg47His) in southern China and the adjacent areas suggests Darwinian positive selection on this genetic locus during Neolithic time though the driving force is yet to be disclosed.
Grab a seat and feast on a giant seafood platter of prawns, clams, crab, langoustines, whelks and winkles (from €25), or just a dozen oysters (€9), accompanied by a bottle of wine and cheeses from the fine selection at the adjacent "fromager-caviste", Laurent Bouvet.
These regions are potentially variable since they are subject to lower selection pressure than the adjacent genes.
We decided to investigate parts of the genome located between 2 open reading frames (ORFs) because they are considered potentially variable since they are subject to lower selection pressure than the adjacent genes.
The adjacent library room is tiny but the selection of books on design and art is excellent.
The design of the TripleTOF5600 quadrupole allows precursor ion selection in a rectangular rather than a Gaussian mass selection window as in other instruments, reducing the co-selection of peptides falling in the adjacent mass windows.
The second half of exon 1 and the adjacent intron were replaced with a PGK1-neo selection cassette in antisense orientation.
In the adjacent aisle, a stout Herero matron examined the meager selection of vegetables.
We surmised that inter-cluster coordination can be strengthened if more channels are between the adjacent clusters and proposed a technique for gateway node selection that ensures that more channels are available for control channel establishment between adjacent clusters.
In addition, we found the co-expression levels of conserved adjacent pairs and non-conserved adjacent pairs to be approximately the same in yeast, indicating that the adjacent relationship of co-expressed pairs is free from selection constraint in yeast.
