title: 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.
