Motif 14, with the A-rich core 5′-[A/C]AACTA-3′, is the second-most overrepresented motif in the upstream regions of the genome, found upstream of 1,366 of the 1,872 genes in 122 of 200 clusters.
Because of the anisotropic shape of metaparticles, the average size and polydispersity of these superstructures are the result of a complicated competition between the energetic drive to expand the A-rich cores and the entropic cost of packing (bumpy) tetrahedra at locally high density.
The best catalyst is Cu@Pt-Ru/CP, having core-shell structure with a Cu rich core and a Pt-Ru rich shell with grain size around 100 nm.
This was largely because the binding sites of both TF families contain an AT rich core and there was an overlap in four positions in these binding sites with high information content.
The alignment of these shorter palindromes shows that they have an AT rich core flanked by 15 bp conserved inverted repeats.
One of the major adhesion structures in macrophages is the podosome, which can be distinguished from other adhesion structures by its characteristic two-part architecture consisting of an F-actin rich core surrounded by a ring structure containing many of the proteins typically found in FA (Linder and Kopp, 2005).
Upon heat-treatment, phase reorganization occurs in hiPP, and the dispersed EP domains can form a multiple-layered core shell structure, comprising a polyethylene-rich core, an EPR intermediate layer and an outer shell formed by EP block copolymer, which accounts to some extent for the good toughness-rigidity balance of the material.
This results in a steady buildup of a helium-rich core, surrounded by a hydrogen-rich outer region.
Germany fears risk-sharing would become risk-shifting, and that any form of fiscal union would likewise turn into a "transfer union", with the rich core permanently subsidising the poorer periphery.
