A cell comprising a synthetic non-naturally occurring oligonucleotide compound comprises nucleotides whose sequence defines a conserved catalytic region and nucleotides whose sequence hybridizes with a predetermined target sequence within a MoMLV Psi packaging sequence on the HIV tat sequence. The catalytic region may be derived from a hammerhead ribozyme, a hairpin ribozyme a hepatitis delta ribozyme, an PNAase P ribozyme, a group I intron or a group II intron. |
