5-Propynyluracil·diaminopurine: an efficient base-pair for non-enzymatic transcription of DNA
Abstract
The Up·D base-pair (5-propynyl uracil·diaminopurine) is found to be more effective at non-enzymatic transcription than the corresponding natural T·A pair; under non-enzymatic reaction conditions where the natural T·A base-pair fails, a DNA template bearing Up efficiently directs the incorporation of D into a product RNA strand.
