    Patent number: 5436330
    Abstract: A DNA fragment is disclosed which has connected to the downstream side of a first DNA sequence containing a region coding for the first ribozyme RNA a second DNA sequence containing a region coding for second ribozyme RNA capable of cleaving by self-processing the 3'-terminus site of the first ribozyme RNA subjected to transcription. A ribozyme having the 3'-terminus site thereof self-processed is obtained by effecting transcription of a RNA using as a template a recombinant vector obtained by recombination by the use of the DNA fragment.
