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
Drug diversion Drug diversion Drug diversion is a medical and legal concept involving the transfer of any legally prescribed controlled substance from the individual for whom it was prescribed to another person for any illicit use. The definition varies slightly among different jurisdictions, but the transfer of a controlled substance alone usually does not constitute a diversion, since certain controlled substances that are prescribed to a child are intended to be administered by an adult, as directed by a medical professional. The term comes from the "diverting" of the drugs from their original licit medical purpose. In some jurisdictions, drug diversion programs
