The links between chromatin spatial organization and biological function
During the last few years, there has been a rapid increase in our knowledge of how chromatin is organized inside the nucleus. Techniques such as FISH (fluorescence in situ hybridization) have proved that chromosomes organize themselves in so-called CTs (chromosome territories). In addition, newly developed 3C (chromatin conformation capture) techniques have revealed that certain chromosomal reg...
متن کاملElaboration of Spatial Function in Political Organization of Space with an Emphasis on Country Divisions in Great Khorasan
One of the aims of spatial political management is to increase access to social and economic services to all residents in an area in order to enhance their satisfaction. There is a great space in the action that has a broad scope. If the spatial political organization implemented in a country is unable to organize such services in a condensed manner, it will face reduced efficiency and la...
متن کاملSpatial organization of axonal microtubules
Several workers have found that axonal microtubules have a uniform polarity orientation. It is the "+" end of the polymer that is distal to the cell body. The experiments reported here investigate whether this high degree of organization can be accounted for on the basis of structures or mechanisms within the axon. Substantial depolymerization of axonal microtubules was observed in isolated, po...
متن کاملSelf-organization of spatial solitons.
We present experimental results on the transverse modulation instability of an elliptical beam propagating in a bulk nonlinear Kerr medium, and the formation and self-organization of spatial solitons. We have observed the emergence of order, self organization and a transition to an unstable state. Order emerges through the formation of spatial solitons in a periodic array. If the initial period...
متن کاملSpatial organization in bacterial chemotaxis.
Spatial organization of signalling is not an exclusive property of eukaryotic cells. Despite the fact that bacterial signalling pathways are generally simpler than those in eukaryotes, there are several well-documented examples of higher-order intracellular signalling structures in bacteria. One of the most prominent and best-characterized structures is formed by proteins that control bacterial...
