Self-assembling RNA square.
The three-dimensional structures of noncoding RNA molecules reveal recurring architectural motifs that have been exploited for the design of artificial RNA nanomaterials. Programmed assembly of RNA nanoobjects from autonomously folding tetraloop-receptor complexes as well as junction motifs has been achieved previously through sequence-directed hybridization of complex sets of long oligonucleot...
متن کاملASSEMBLE TIME FOR SELF-ASSEMBLING SQUARE TILES - JAMES SOLBERG 1 Assemble time for self-assembling square tiles
As technology drives components smaller, traditional methods of assembling these components become ever more impractical. Self-assembly is a viable solution in which the individual components autonomously organize themselves without the external guidance of a supervising agent. In this paper we look at the assembly times for various one and two dimensional objects that are assembled with square...
متن کاملSelf-Assembling Robots
One of the grand challenges of robotics is the design of robots that are adaptive and self-sufficient. This can be crucial for robots exposed to environments that are unstructured (in space and time) or not easily accessible for a human operator, such as the inside of a blood vessel, a collapsed building, the deep sea, or the surface of another planet.Modular reconfigurable robots are among the...
متن کاملTectoRNA and 'kissing-loop' RNA: atomic force microscopy of self-assembling RNA structures.
RNA molecules have been much less studied by atomic force microscopy (AFM) than have DNA molecules. In this paper, AFM imaging is presented for two different RNA molecules able to self-assemble into complex supramolecular architectures. The first one is a molecular dimer of a 230-nt RNA fragment coming from the RNA genome of a murine leukaemia virus. The monomeric RNA fragment, which appears by...
متن کاملSelf-Assembling Dynamical Hierarchies
This paper addresses the open problem of assembling multilevelled hierarchical structure. It presents a model of an infinitely-levelled, self-assembling dynamical hierarchy which arises from the interaction of geometric primary elements with a fixed complexity. A formal description of the presented hierarchy is derived. This quantifies the relative compression achieved by describing the system ...
