Natural selection of specific protobiomonomers during abiogenic development of the prototype genetic code is hindered by the diversity of structural, spatial, and rotational isomers that have identical elemental composition and molecular mass (M), but can vary significantly in their physicochemical characte...
An analysis has been performed of stress odor as a universal criterion allowing the predator to estimate the vulnerability of potential prey. Selective elimination of unhealthy (stressed) individuals by predators is a mechanism of natural selection for increased adaptation of populations and species to ...
With Natural Factors’ unprecedented quality control and a large selection of supplements, we feel confident in guiding our customers towell-being. Nanaimo's Health Shop Our Nature At Natural Factors, we care. We care about the source and purity of our products. We care about being good stewar...
Treatment with an antagonizing tailocin results in a few very high, replicable, positive gene fitness scores (up to +16), indicative of reliable selection for a very small subset of mutants (Fig.2C). These genes are clearly important for tailocin sensitivity. However, the competitive advantage...
of growth factors. Immunochemical detection of BrdUrd can be used to determine proliferative characteristics of differentiating tissues and to obtain birth dates for actual differentiation events. Studies are also described in which BrdUrd is used follow the order of DNA replication in specific chromaso...
Transcription factors (TFs) control specificity and activity of gene transcription, but whether a relationship between these two features exists is unclear. Here we provide evidence for an evolutionary trade-off between the activity and specificity in human TFs encoded as submaximal dispersion of aromati...
Environmentally-induced fluctuation in the form and strength of natural selection can drive the evolution of morphology, physiology, and behavior. Here we ... Carlos,A.,Botero,... - 《Plos One》 被引量: 76发表: 2012年 Mating skew in Barbary macaque males: the role of female mating synchron...
Thereby, the selection of the companies was based on both access (Alexander & Smith, 2019) and theoretical sampling (Lincoln & Guba, 1985). The key data source was represented by extensive qualitative thematic (Eisenhardt & Graebner, 2007; King & Horrocks, 2010) and ethnographic face-to-face...
Adult fireflies exhibit unique flashing courtship signals, emitted by specialized light organs, which develop mostly independently from larval light organs during the pupal stage. The mechanisms of adult light organ development have not been thoroughly s
a, Selection of 290 high-confidence TFs as target genes with human homologs or worm-specific TFs with potential interest in cell differentiation. Right: TF classes based on typical domains. Classes with less than three TFs are not included. b, Maximum projections of 3D images showing cellular ...
