The Cucurbita maxima ribosomal DNA intergenic spacer has a complex structure
Gene, 1989The nucleotide (nt) sequence of the 5508-nt intergenic spacer (IGS), between the 25S- and the 18S-coding regions of Cucurbita maxima rDNA, was determined. The fragment sequenced is 6142 nt long and includes 472 nt of 25S- and 162 nt of 18S-coding regions.

Ternary DNA chip based on a novel thymine spacer group chemistry
Colloids and Surfaces B: Biointerfaces, 2015A novel thymine-based surface chemistry suitable for label-free electrochemical DNA detection is described. It involves a simple two-step sequential process: immobilization of 9-mer thymine-terminated probe DNAs followed by backfilling with 9-mer thymine-based spacers (T9).

Cell-Specific Ribosomal DNA Spacer Variability in Human Urothelial Carcinoma Cultures
Journal of Urology, 1987Length variation of a ribosomal DNA "spacer" region in four chromosomally characterized transitional cell carcinoma cultures was analyzed by restriction endonuclease cleavage and Southern blotting. Cell lines with relative karyotypic conservation, such as UM-UC-2 (modal chromosome number 48, four marker chromosomes) demonstrate little change in the ...

Ribosomal DNA ITS-1 Intergenic Spacer Polymorphism in Triatomines (Triatominae, Heteroptera)
Biochemical Genetics, 2005The length polymorphism of ribosomal DNA ITS-1 intergenic spacer was analyzed in eight species of triatomines belonging to Triatoma, Rhodnius, and Panstrongylus genera. The analyzed species were Rhodnius domesticus, R. neivai, R. robustus, Triatoma brasiliensis, T. infestans, T. vitticeps, Panstrongylus megistus, and P. herreri.

Sequence Characterization of a Unique Intergenic Spacer in Gadiformes Mitochondrial DNA
Marine Biotechnology, 1999: The nucleotide sequences of intergenic spacers located between the tRNA(Thr) and tRNA(Pro) genes in mitochondrial DNA of cod fishes (order Godiformes) were determined. Spacers from eight species representing two families of cod fishes were analyzed and found to vary in size from 25 to 99 bp.

Langmuir, 2018
DNA origami nanotechnology is being increasingly used to mimic membrane-associated biophysical phenomena. Although a variety of DNA origami nanostructures has already been produced to target lipid membranes, the requirements for membrane binding have so far not been systematically assessed.

Investigation of DNA–cationic bolaform surfactants interaction with different spacer length
Colloids and Surfaces B: Biointerfaces, 2013In this paper interaction of DNA with cationic bolaform surfactants is investigated. The structural formula for synthesized bolaforms is as follows: bolaform B1 with structural formula Br(-)(CH3)3N(+)(CH2)3N(+)(CH3)Br(-) and bolaform B2 with structural formula of Br(-)(CH3)3N(+)(CH2)12N(+)(CH3)Br(-).

DNA sequence analyses of the ribosomal spacer regions in theTriticeae
Plant Systematics and Evolution, 1988Two regions of the ribosomal DNA (rDNA) were sequenced from a range of species from the tribeTriticeae. One region, the central spacer, was found to be more divergent in sequence than the other, the 18 S-spacer junction. Both regions contained sequences 20–30 bp long which were more highly conserved than the remainder of the region and their possible ...

The eukaryotic CCAAT and TATA boxes, DNA spacer flexibility and looping
Journal of Theoretical Biology, 1992Regulation of RNA transcription in eukaryotic polymerase II promoters involves a complex assembly of protein factors. Some of the factors bind to their cognate DNA-sequence elements while others mediate between the DNA bound ones. In order to enable protein-protein interaction, their spatial positioning with respect to each other is critical.

DNA crossover flexibilities upon discrete spacers revealed by single-molecule FRET
Soft MatterScheme of complementary DNA duplex spacer linked two origami structures. A longer duplex spacer (large L) increased the angle α as well as FRET distance (d). Here, dihedral angle β is assumed to be zero.
