Mismatched base pairing in RNA crystal structures
International Journal of Quantum Chemistry, 1999Non-Watson–Crick base pairs or mismatches in RNA crystal structures have been summarized and their effects on the geometry of RNA molecules and their biological implications have been discussed. The mismatches can distort the helical structures by producing kinks/bends and can increase or decrease the major groove width, depending on the sequence.

Tunable spin-selective transport through DNA with mismatched base pairs
Journal of Physics: Condensed Matter, 2014In our theoretical analysis of spin-selective transport through a homogeneous poly(G)-poly(C) DNA we explore the influence of a mismatched base pair in the DNA chain. The spin polarization of the electrical current through DNA is strongly sensitive to the presence of the mispair in a DNA with less than 20 base pairs. Replacing a canonical G-C base pair

EFFECT OF MISMATCHED BASE PAIRS ON DNA PLECTONEMES
2022Base pair mismatches in DNA occur during replication and can result in mutations and certain types of cancer. The exact mechanism by which mismatch repair proteins recognize mismatches is still not well understood. Structures of mismatch recognition proteins bound to a mismatch indicate that the process involves introducing a sharp bend in the DNA and ...

Effect of base pair mismatches on recombination via the RecBCD pathway
Molecular and General Genetics MGG, 1989The effect of base pair mismatches on recombination via the RecBCD pathway was studied in mutS and wild-type Escherichia coli, using substrates that contain single or multiple mismatches. Recombination between homologous DNA inserts in lambda phage and pBR322-derived plasmids forms phage-plasmid cointegrates that result from an odd numbers of ...

Electroanalysis, 2011
AbstractAn electrochemical approach for single base‐specific detection of label‐free target single‐strand DNA (ssDNA) was demonstrated. The approach was based on the high ligation selectivity of Taq DNA ligase coupled with ferrocenated gold nanoparticle/streptavidin conjugate‐based voltammetric detection method. The ferrocene (Fc) moieties of Fc‐capped
