Budr

Budr

(Science: chemical molecular biology) analogue of thymidine that induces point mutations because of its tendency to tautomerisation: in the enol form it pairs with g instead of a.

It is used as a mutagen and also as a marker for dna synthesis (the incorporation of budr can be recognised because the staining pattern differs: an even more sensitive method uses a monoclonal antibody staining procedure.)
