Another feature of origins is that they typically contain an AT-rich region to facilitate dissociation of the DNA during replication initiation [ 17].
A preference for AT-rich sequences has also been reported for D. melanogaster ORC (MacAlpine et al., 2004), which additionally appears to localize predominantly at active promoters with open chromatin structure (MacAlpine et al., 2010), a feature of origins also observed in S. cerevisiae (Eaton et al., 2010).
In model 2 of Table 3, only the significant educational system features of origin and destination countries are presented.
The focus of this study was on educational system features of origin and destination countries and their relation with the educational performance of 15-years old migrant children.
The bonus feature "Point of Origin: Inside the Unaired Pilot" on the Numb3rs: The Complete First Season DVDs highlights the differences between both pilots and features clips from the original pilot.
This paper generalizes and extends classical traffic assignment models to characterize the statistical features of Origin-Destination (O-D) demands, link/path flow and link/path costs, all of which vary from day to day.
The characteristics of pain paroxysms were carefully evaluated, including temporal features (duration and frequency) and spatial features (site of origin, trajectory, and site of ending).
X-ray photoelectron spectroscopy (XPS) spectra of sputter-etched nc-TiC/a-C nanocomposite thin films published in literature show an extra feature of unknown origin in the C1s region.
These data illustrate that MS/MS experiments could be performed on every feature of biological origin over a minimal and feasible number of analytical runs.
CpG sequences may also be a feature of mammalian origins, which appear to be enriched at promoters, though are also found frequently within genes (Cadoret et al., 2008; Karnani et al., 2010; Cayrou et al., 2011; Sequeira-Mendes et al., 2009).
We believe that the simple models studied here illustrate several essential features of the origin of life problem as it occurred in the real world, i.e. the origin of life is a transition between two alternative steady states of a chemical reaction system that is driven by stochastic concentration fluctuations involving relatively small numbers of molecules in a localized region of space.
