The phrase "arm junction" is not a standard or commonly used expression in written English.
It could potentially be used in a specific context related to anatomy or engineering, referring to a point where arms or arm-like structures meet.
Example: "The arm junction of the robot allows for greater flexibility and movement."
Alternatives: "elbow joint" or "arm connection".
In the case of the RNA cube scaffolds, the previously generated and tested RNA cube model was mated with separately generated multiple alteRNAtive models of a helix and siRNA arm junctions generated with the aid of RNA2D3D, MC-Sym, and RNAComposer.
An examination of the maps of all the human chromosomes available on the web http://www.ensembl.org/Homo_sapiens/mapview chr failed to yield any more information in this regard, as most arm junctions within the alphoid contigs reported therein lacked highly homogeneous alpha satellite HORs.
One of the simplest branched structures is a four-arm junction that consists of four individual DNA strands, portions of which are complementary in a specific pattern.
Each crossover point is itself topologically a four-arm junction, but is constrained to a single orientation, as opposed to the flexible single four-arm junction, providing a rigidity that makes the DX motif suitable as a structural building block for larger DNA complexes.
Unlike in natural Holliday junctions, each arm in the artificial immobile four-arm junction has a different base sequence, causing the junction point to be fixed at a certain position.
To identify X centromere-specific markers suitable for ChIP, genomic sequence spanning 450 kb of Xp pericentromere, 350 kb of Xq pericentromere, and regions 150 kb from Xp and Xq centromere-arm junction was analyzed in silico using UCSC Genome Browser (March 2006) human reference sequence assembly (NCBI Build 36.1).
The assembly begins with the sequential opening of the A1, A2, and A3 hairpins causing self-assembly of a three-arm junction corresponding to the first vertex of the tetrahedron (reactions 1 3).
BBB appeared as a three-arm junction, CBB as a single triangle, CCB as a double triangle, and CCC as a flattened tetrahedron, all consistent with their designed shapes.
While the unique mobility of the CCC band indicates that all nine strands are incorporated into a single complex, additional assays are required to demonstrate ring formation and distinguish it from, for example, a large floppy three-arm junction.
For perpendicular bound molecules, the average position of a freely rotating head would be located slightly above the lever arms' junction.
synthetic 3-arm junctions in which the 3'-ends of three oligonucleotides are connected by a suitable linker.
