Abstract: An oligonucleotide is intended to be used as a promoter non-template strand in the transcription of a sequence of a nucleotide target in the presence of a phage RNA polymerase. The phage RNA polymerase has specific natural promoters containing a consensus sequence from at least position -17 to position -1. The oligonucleotide contains a core sequence flanked at at least one of its ends by a nucleotide sequence capable of hybridization with a sequence of the target. The core sequence contains a sequence of 6 to 9 consecutive nucleotides from the region -12 to -4 of the non-template strand of the specific promoter, or a sufficiently homologous sequence to enable the functionality of the RNA polymerase to be retained.
