A second major difference between A-form and B-form nucleic acid is the placement of base-pairs within the duplex. In B-form, the base-pairs are almost centered over the helical axis but in A-form, they are displaced away from the central axis and closer to the major groove. The resul...
The structures of B-form and A-form DNA are studied in 0–70 and 70–80% ethanol solutions, respectively, in an electric field, using linear dichroism. The limiting reduced linear dichroism data of B-form DNA are chain length dependent in 0% ethanol solution. However, there is no such ...

The abrupt extension of the contour length and the self-unwinding of the double helix in the transition from theB-form toS-form of a double-stranded DNA under a stretching force is investigated in the framework of the model with basepair interactions and bending [Phys. Rev. Lett.22, 4560 ...

Mitochondrial DNA (mtDNA) encodes essential subunits of the oxidative phosphorylation system, but is also a major damage-associated molecular pattern (DAMP) that engages innate immune sensors when released into the cytoplasm, outside of cells or into circulation. As a DAMP, mtDNA not only contribute...
Oligonucleotide-based technologies for biosensing or bio-regulation produce huge amounts of rich high-dimensional information. There is a consequent need for flexible means to combine diverse pieces of such information to form useful derivative outputs,
