that consist of a purine on one strand joined to a pyrimidine on the other strand by hydrogen bonds holding together the two strands much like the rungs of a ladder and that include adenine linked to thymine in DNA or to uracil in RNA and guanine linked to cytosine in both DNA and RNA...

of four types of lesions—uracil, 8-oxo-7,8-dihydroguanine, spiroiminodihydantoin and abasic sites by the dNaM·d5SICS UBP in a one-pot, four-step reaction sequence (Figs 3aand4a). The elegance of this system lies in the ability to PCR amplify the third base pair, which effectively...
A one and two-dimensional nuclear magnetic resonance study of a non-selfcomplementary oligonucleotide containing a central 5-bromouracil—guanine pair is reported. For these two bases three types of hydrogen bonding schemes could exist; wobble, rare tautomer and ionized. The two-dimensional spectra ...

Radical formation in monocrystals of equimolar complexes of 9-ethyl adenine: 1-methyl uracil by irradiation with X-rays was investigated at 77 K and 300 K using e.s.r.-spectroscopy at 9路5 GHz and 35 GHz. Five different types of spectrum were identified, which corresponded to spectra of ...
