Abstract
RNA may be transcribed using a nucleotide reagent as the promoter. The reagent may enable RNA to be transcribed without sequence specification and without protein cofactors, by means of an RNA polymerase that is known to be DNA-dependent such as the RNA polymerase of the phage T7, or by means of new, mutated RNA polymerase with the ability to synthesize a transcription product of polynucleotide matrix with a higher yield when the matrix is RNA than when the matrix is DNA. This type of RNA polymerase can be obtained by effecting mutations on a coding gene for a wild-type RNA polymerase, and then by selecting the mutated RNA polymerase with the ability. The invention can be applied notably to the detection, synthesis or quantification of RNA.
