    Abstract: A recombinant DNA vector is provided as a universal transcription vector having a replication origin and selectable marker, a promoter and a transcription initiation site comprising a first transcribed nucleotide, wherein a restriction site is provided immediately adjacent to and upstream from the transcription initiation site so as to seprate transcribed from untranscribed nucleotides. A second restriction site may also be positioned downstream from the said restriction site. Precise control of initiation and termination of transcription is attained by this invention. Such control is important in assuring the effectiveness of transcribed RNA viral vectors.A high fidelity in vitro RNA transcription method is also provided utilizing vectors constructed from the universal transcription vector, or other vectors producing transcripts having no more than one extra 5' base. This method is capable of producing functional RNA transcripts, preferably comprising infectious viral sequences.
