A Sensitive Fluorescence Biosensor for Silver Ions (Ag+) Detection Based on C-Ag+-C Structure and Exonuclease III-Assisted Dual-Recycling Amplification by Yubin Li, Jiaming Yuan, Zexi Xu

“…Since oligo-1 involves C-C mismatches, the presence of Ag+ can be captured to form C-Ag+-C base pairs, which results in a double-helix structure with a blunt terminus. The double-helix structure can be cleaved by EXO III to release short mononucleotide fragments (trigger DNA) and Ag+. …”

Physiological Roles of DNA Double-Strand Breaks by Farhaan A. Khan, Syed O. Ali

“…Among the most cytotoxic lesions is the DNA double-strand break (DSB) which arises from the cleavage of both strands of the double helix. Cells boast a considerable set of defences to both prevent and repair these breaks and drugs which derail these processes represent an important category of anticancer therapeutics. …”

Use of Nucleic Acid Analogs for the Study of Nucleic Acid Interactions by Shu-ichi Nakano, Masayuki Fujii, Naoki Sugimoto

“…Remarkably, they can adopt two different conformations responding to their interaction energies, and one of them is the stacking conformation of the nonpolar aromatic group causing the site-selective flipping of the opposite base in a DNA double helix. The base pair-mimic nucleosides can be used to study the mechanism responsible for the base stacking and the flipping of bases out of a nucleic acid duplex.…”

Molecular mechanisms of photosensitization induced by drugs XIV: Two different behaviours in the photochemistry and photosensitization of antibacterials containing a fluoroquinolon... by G. De Guidi, S. Giuffrida, S. Monti, P. S. Pisu, S. Sortino, L. L. Costanzo

“…DNA presents peculiar features with respect to that vs. membranes, probably due to a specific binding of the drugs to the double helix and to the operativeness of different photosensitization mechanisms with the two types of biosubstrates. …”

Foldback Intercoil DNA and the Mechanism of DNA Transposition by Byung-Dong Kim

“…Foldback intercoil (FBI) DNA is formed by the folding back at one point of a non-helical parallel track of double-stranded DNA at as sharp as 180° and the intertwining of two double helixes within each other's major groove to form an intercoil with a diameter of 2.2 nm. …”
