[RNA synthesis using T7 phage RNA polymerase: transcription of synthetic DNA templates in solution and on polymer support].

Transcription of synthetic DNA by T7 RNA polymerase was used to obtain oligoribonucleotides of defined sequence. The enzyme's ability to transcribe DNA immobilized on hydrazide-sepharose was revealed. DNA templates used in such synthesis can be constructed by means of enzymatic (DNA ligase) or chemical ligation (cyanogen bromide).
