Sentence examples for undergoing the drift from inspiring English sources

Still, it seems that these genomes are also undergoing the drift duplication to some degree.

The high mutation rate that occurs during replication of the virus and selection of neutralisation-escape variants by pre-existing antibodies, leads to the virus undergoing "antigenic drift" within populations, such that a particular influenza vaccine usually confers protection for only a few years.

All the specimens studied in this program were shown to undergo the 0.05 rad total story drift with the AISC seismic provision requirements being satisfied.

Of concern is that these influenza A viruses might undergo the genetic changes of antigenic drift into novel pathogenic forms (2 ), triggering human influenza pandemics (3 ).

Over the entirety of North and South America, where native populations have undergone extreme drift, the estimate of the total among-group mtDNA variance is 26% [48], close to the estimate for Northern Island Melanesian populations.

Crucially, the topological properties of genes undergoing epigenetic drift were highly distinctive from those which have been associated with modulating longevity, those undergoing age-related changes in expression, or those somatically mutated in age-related diseases like cancer.

In fact, in order for the quasispecies not to undergo genetic drift, the neutral space around a fitness peak should be sufficiently small to be completely explored by the population.

These analyses indicate that LPAI H5N2 viruses in Mexico are constantly undergoing genetic drift and that serosurveillance of AI viruses is significantly influenced by the antigen or antisera used for the HI test.

Our results suggest that (i) Bornean elephants probably derive from a very small female population, (ii) they rarely disperse across current human-dominated landscapes that separate forest fragments, and (iii) forest fragments are predominantly comprised of populations that are already undergoing genetic drift.

In fact, it was shown that LPAI H5N2 viruses in Mexico are constantly undergoing genetic drift, and that recent AI virus isolates have significant antigen divergence when compared to the AI vaccine strain [ 7].

As there are very few introns in yeast transcripts, prediction of uORF conservation has been attempted in S. cerevisiae by analyzing genomic sequence upstream of predicted mORF start sites [ 23], but it is still not clear whether these uORFs are truly conserved (i.e., are under negative selection pressures), or are simply undergoing evolutionary drift.
