NAD, or nicotine adenine dinucleotide, probably needs no introduction. Together with its primary alter-egos NADH, NADP and NADPH, our private suite of pyridine-based nucleotides serve as hydride donors in some 400 enzymatic ...
New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now—precisely how the copying of genetic material that, once started, is properly turned ...
