Digitalis purpurea detect DNA or RNA. It can easily be attached to nucleotides by chemical modifications. DIG molecules are often linked to uridine nucleotides; DIG-labeled uridine (DIG-U) can then be incorporated into RNA probes via "in vitro" transcription. Once hybridisation occurs "in situ", RNA probes with the incorporated DIG-U can be detected with anti-DIG antibodies conjugated to alkaline phosphatase. To reveal the hybridised transcripts, alkaline phosphatase can be reacted with a chromogen to produce a coloured precipitate. The colours of the petals of the "Digitalis purpurea" are known to be determined by at least three genes that interact with each other. The
