How can you use “nmr” in a sentence? Here are some example sentences to help you improve your vocabulary:
Earlier studies have shown that DAP, in DNA fragments, can widen the minor groove, as detected by reactivity towards uranyl nitrate or susceptibility to Dnase cleavage [ 29 ] , and can relieve compressions in the minor groove associated with A-tracts [ 30 ] . In contrast, NMR and molecular modeling studies of an oligonucleotide duplex containing MeC have demonstrated that, while this duplex still has a B-DNA conformation, there are differences in the structural parameters and thermal stability relative to the unmodified duplex [ 31 ] . An earlier study also found, in two closely related octanucleotide duplexes, that although the methylated duplexes retained their B-DNA conformation, different structural and thermal stability effects were seen [ 32 ] . Although these studies have been carried out with DNA-DNA and not DNA-RNA duplexes, it is possible that MeC substitution may have different structural consequences than DAP substitution.
Crude products were purified by silica gel column chromatography using chloroform:hexane (7:3) to give 22 in 77% yield [ 31P NMR 105.
The separation of intracellular from extracellular water NMR signals is restricted to roots or other tissues, such as some stems, which have elongated cells oriented in parallel [ 70] and is illustrated in Figure 6for maize roots.
An NMR structural analysis of the HRD domain of Sgs1p and models for the WRN and BLM domains suggests that this region is a single-strand nucleic acid binding domain that functions as an accessory DNA binding region with the helicase domain [ 41].
The claim that such turbidity did not affect 13C-NMR measurements [ 3 5 6 ] contrasts with evidence that even small multimers can change NMR chemical shifts [ 25 26 ] . It should be noted also that, at high concentrations of B =, extensive, reversible self-association of B =can lead to apparently stable supersaturation with no separation of an insoluble phase [ 2 ] . For example, at pH 8.5 and a UCB concentration of 20 μM (63 times S), the weight-average aggregation number of UCB has been found to be 7.17 [ 18 ] , corresponding to a molecular weight of 4,195.
