Thus, although this function is not habitat-restricted presently, it may have conferred an ecological advantage to the ancestor of some present-day Lachnospiraceae.
It may be the case that some risk alleles are positively selected individually or as components of an abstract biological function due to a presently unknown benefit they confer on the host.
Samples generated from this field collection are being used presently for more molecular and genetics analysis such as the study of the gene expression pattern of the detoxification genes by microarray or the genetic mapping of genes conferring these resistances using family samples generated from this collection.
While this has made identification of new species easier in some cases, the consideration of arbitrary cutoff values based on similarity in selected genes like 16S rRNA (presently 99% with16S rRNA) as a yardstick to confer species status may sometimes be fraught with the danger of losing out on microbial diversity.
Folate depletion appears to enhance carcinogenesis, whereas folate supplementation above what is presently considered to be the basal requirement confers a protective effect [ 180].
The filaggrin locus on chromosome 1q21 – 22 is presently the most clearly recognizable genetic locus where mutations confer a predisposition for familial atopic dermatitis and asthma [ 28].
Due to the diversified health benefits conferred by them, they have earned a prominent recognition as Nutraceuticals presently limelighted in the health market.
Mr Cameron rushed back from his break in Cornwall to confer with ministers in London.Confusion already surrounds the work Britain's armed forces are presently performing in Iraq.
The high carrier frequency in affected populations suggests the selective advantage conferred by the heterozygous state but no perceptible biological advantage of the carrier state is presently identified [49].
Nevertheless, some conclusions can be made on the basis of the presently known channels: it seems likely that the linked four-domain structures of NaV and CaV channels conferred an evolutionary advantage, in the kinetics of channel activation, inactivation, or recovery from inactivation, but it seems less likely that the four-domain structure evolved to provide ion selectivity.
How this affects its function is presently unknown although it is possible that in the absence of its ability to interact with partner proteins may confer a very different function to the protein.
