Researchers from Japan enhanced the hydrogen evolution reaction (HER) by modifying platinum cathodes with purine bases. The purine molecules form hydrogen-bonded cages with surrounding water, which ...

Depurination of DNA and RNA sequences is an alteration of the sugar-phosphate backbone in which hydrolysis of a purine base (adenine or guanine) occurs. Synthetic oligonucleotides suffer from such ...

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...

A NUMBER of methods have been published for the column chromatographic separation of the purine and pyrimidine bases 1. The shortcomings of these are their slow rates of flow and the fact that the ...
