Sentence examples for orientation of base from inspiring English sources

In NAPSS-CS, experimental chemical shifts for GH1, UH3, and UH5 in GU pairs, AH2, UH3, and UH5 in AU pairs, and GH1 in GC pairs can be input, which may define the orientation of base pairs in helices (Table 2 ).

Carboxylate-substituted cytosine is the only case considered here that loses the approximately parallel orientation of bases.

NMR spectra reveal that r CCCC) has an A-form-like folded-state structure with C3′-endo sugar puckers, an anti orientation of bases relative to their sugars, and base base stacking.

To remedy this, we replace the incorrect nucleoside base atoms with the correct ones while maintaining the orientation of the base plane.

With regard to structural heterogeneity of εdA adduct, NMR analyses have revealed that orientation of the base around the glycosydic bond is affected by identity of nucleotide opposite the lesion (21, 22).

Switching the orientation of the base pairs (snR30 st1) or transition of the purines and pyrimidines (snR30 st2) with simultaneous alteration of the A601 and G602 tail nucleotides preceding the ACA box had no effect on the accumulation of the mutant snR30 RNAs in transformed GAL∷snR30 cells (lanes 5 and 6).
