Water disinfection processes may generate several dangerous substances that can affect both human beings and the environment. As a known contaminant in drinking water, the compound 2,6-dichloro-1,4-benzoquinone (DCBQ) and its degradation products in

In this work, we study the adsorption of poly(rA) on graphene oxide (GO) using AFM and UV absorption spectroscopies. A transformation of the homopolynucleotide structure on the GO surface is observed. It is found that an energetically favorable confo

The homopolynucleotide (homo-oligonucleotide) tracts function as regulatory elements at various stages of mRNAs life cycle. Numerous cellular proteins specifically bind to these tracts. Among them are the different poly(A)-binding proteins, poly(C)-b

As a first step in testing the possibility of correlation calculations of extended systems using localized orbitals, localization of the canonical Hartree-Fock orbitals of the four nucleotide bases was performed. The results show an excellent localiz

The influence of Cd2+ ions on the conformational equilibrium of single-stranded (poly(U), poly(A), poly(I)) and triple-stranded polyribonucleotides (A2I, A2U) in aqueous solutions (0.1 M Na+ pH 7) has been investigated using difference UV spectroscop

A new homopolynucleotide triple helix, (dT)n.2(dA)n, detected by circular dichroism mixing curves, is the product of an endothermic reaction of (dA)n.(dT)n with (dA)n at moderate temperatures and high salt concentrations ([NaCl] > or = 2.6 M): (dA)n.
