Disclosed are methods for determining DNA nucleotide sequences comprising reacting ribonucleoside 5'- triphosphates and 3'-dNTP derivatives in the presence of an RNA polymerase modified so as to enhance its ability for incorporating the 3'-dNTP derivatives and a DNA fragment containing a promoter sequence for the RNA polymerase to obtain a nucleic acid transcription product, separating the resulting nucleic acid transcription product, and determining a nucleic acid sequence from the resulting separated fraction. These methods can produce a transcription product of a long chain and afford more accurate sequence data where fluctuation of signals from labeled deoxyribonucleotides is reduced.

L'invention porte sur un procédé de séquençage de l'ADN consistant à faire réagir un ribonucléoside 5'-triphosphate avec un dérivé de 3'dNTP en présence d'un ARN polymérase muté qui a été modifié de façon à améliorer sa capacité à absorber le dérivé de 3'dNTP et un fragment d'ADN contenant une séquence promoteur de l'ARN polymérase, à séparer le produit de transcription de l'acide nucléique ainsi obtenu et à lire la séquence de l'acide nucléique à partir de la fraction séparée. Il est possible, par ce procédé, de former un produit de transcription à longue chaîne et d'obtenir, à partir des désoxyribonucléotides marqués, des données de séquence plus précises avec peu de modifications dans les signaux.
