  "abstract": "This invention provides chimeric DNA/RNA catalytic molecules useful to cleave RNA sequences.",
  "claims": [
    "1. A catalytic molecule capable of cleaving an RNA sequence at a known ribozyme cleavage site said molecule having the formula 3' X - AAAG - Y - AGUAAGUC - Z 5' or 3' X - CAAAG - Y - AGUAAGUC - Z 5' in which X and Z are DNA sequences that base pair with an RNA substrate at positions juxtaposed to said known cleavage site, AAAG, CAAAG and AGUAGUC are RNA sequences, Y is a DNA sequence that base pairs inter se in a manner required to permit said RNA sequences to cleave said substrate at said cleavage site.",
    "2. A catalytic molecule capable of cleaving an RNA sequence, said molecule having catalytic RNA moieties linked to first and second DNA moieties which base pair with the substrate RNA sequences flanking the cleavage site and interconnected by a third DNA sequence which base pairs inter se to facilitate said cleavage.",
    "3. A molecule including the construct shown by FIG. 1 or FIG. 2."
