From an evolutionary point of view, merging of two divergent genomes (hybridization) and doubling of an existing genome, either of one genome (autopolyploidy) or a hybrid genome (allopolyploidy) represent revolutionary events often with cardinal biological effects, as they may lead to rapid organismal diversification and even stasipatric speciation [ 41, 42].
Thus, at least in the case of monoallelic silencing, the transcriptional competency of a gene can be defined as existing in either of two states.
Scientists in training need to learn to take advantage of the vast and rapidly growing storehouse of existing knowledge, "either through their own skills or through tapping into the skills in partnerships or through the tools that they are able to convene," Goble says.
An important role can also be attributed to Evidence Based Medicine (EBM), a movement essentially based on secondary analyses of existing data (either literature or data) which, by using systematic review and meta-analysis, aims to identify which health intervention actually works and should thus be implemented in health care.
An out of possession title affidavit expressly waives an ownership right existing by way of either of two similar legal concepts called adverse possession or a prescriptive easement.
For resource optimization and time constraints, it is often desired to estimate and predict certain material properties of hot-mix asphalt (HMA) from a known set of existing data, generated either through laboratory or field testing; typically for the purposes of design and/or analysis.
This study also discusses the influence of hydrogen species existing in either precursor ions or graphenes on the formation of uniform and well-dispersed NPs on the substrates.
Because of the existing controversy for either one of the described hypothesis, namely mesialization of posterior molars or a distoangulation of the molar crown with a concomitant mesialization of their roots, the purpose of this study was to determine the effect of the MPDD on the sagittal inclination of maxillary molars in open bite individuals with different sagittal malocclusions.
The ongoing identification of novel viruses as well as modifications of existing ones based either on rational design or directed evolution have generated vector variants with improved transduction properties.
"But we show quite clearly there was not complete replacement of existing populations by either Anglo-Saxons or Danes.
