It catalyzes the 5' => 3' synthesis of RNA on either single-stranded DNA or double-stranded DNA downstream from it promoter
Incorporates modified nucleotides (e.g., aminoallyl-, biotin-, fluorescein-, digoxigenin-labeled nucleotides) Recommended for: Synthesis of unlabeled and labeled RNA that can be used:for hybridization, in vitro RNA translation; as aRNA, siRNA, substrate in RNase protection assays, template for genomic DNA sequencing
Note: Consensus promoter sequences: TAATACGACTCACTATA G GGAGA
The position in bold (+1) indicates the first nucleotide incorporated into RNA during transcription
Only bases at this position through +3 are critical for transcription, and they must be a G and a purine base, respectively.
