DNA-Mediated Electrochemistry [PDF]
, 2008 The base pair stack of DNA has been demonstrated as a medium for long-range charge transport chemistry both in solution and at DNA-modified surfaces. This chemistry is exquisitely sensitive to structural perturbations in the base pair stack as occur with

Calculation of the Stabilization Energies of Oxidatively Damaged Guanine Base Pairs with Guanine
Molecules, 2012 DNA is constantly exposed to endogenous and exogenous oxidative stresses. Damaged DNA can cause mutations, which may increase the risk of developing cancer and other diseases. G:C-C:G transversions are caused by various oxidative stresses. 2,2,4-Triamino-

Identification of a novel cytosolic aldehyde dehydrogenase allele,
Human Genomics, 2009 This paper reports the identification of a novel cytosolic aldehyde dehydrogenase 1 (ALDHIAI) allele. One hundred and sixty-two Indo-Trinidadian and 85 Afro-Trinidadian individuals were genotyped.

Hoogsteen base pairs proximal and distal to echinomycin binding sites on DNA [PDF]
, 1987 Forms of the DNA double helix containing non-Watson-Crick base-pairing have been discovered recently based on x-ray diffraction analysis of quinoxaline antibiotic-oligonucleotide complexes.

Quantum Logic Gates Based on DNAtronics, RNAtronics, and Proteintronics
Advanced Intelligent Systems, 2021 Quantum computers (QCs) adopt an n‐state quantum mechanical system to manipulate the superposition state. However, molecular transistors are not used to build up the quantum logic gate.

Characterization of the trans Watson-Crick GU base pair located in the catalytic core of the antigenomic HDV ribozyme. [PDF]
PLoS ONE, 2012 The HDV ribozyme's folding pathway is, by far, the most complex folding pathway elucidated to date for a small ribozyme. It includes 6 different steps that have been shown to occur before the chemical cleavage.

Frontiers in Chemistry, 2019 Single nucleotide polymorphisms (SNPs) affect base pair stacking, which is the primary factor for maintaining the stability of DNA. However, the mechanism of how SNPs lead to phenotype variations is still unclear. In this work, we connected SNPs and base

DFT study on metal-mediated uracil base pair complexes
Journal of Saudi Chemical Society, 2017 The most stable of metal-mediated uracil base pair complexes were determined. Method was used density functional theory, B3LYP. The calculations of systems containing C, H, N, O were described by 6-311++G(d,p) and cc-PVTZ basis sets and LANL2DZ and SDD ...

The base-pairing ability of the base pair-mimic nucleosides [PDF]
Nucleic Acids Symposium Series, 2007 The deoxyadenosine derivative tethering the phenyl group at N6 of deoxyadenosine (A(phe)) was previously found to have a property to stack strongly with adjacent nucleotide bases in a DNA duplex. On the other hand, it was also demonstrated that DNA polymerases selectively incorporated dTTP opposite A(phe) in a template DNA strand.
