160 results about "Operon gene" patented technology

The present invention relates to a first group of novel viral and human associated oligonucleotides, here identified as “Genomic Address Messenger” or “GAM” oligonucleotide, and a second group of novel operon-like viral and human polynucleotides, here identified as “Genomic Record” or “GR” polynucleotide. GAM oligonucleotides selectively inhibit translation of known “target” genes, many of which are known to be involved in various viral diseases. Nucleic acid molecules are provided respectively encoding 1,655 viral and 105,537 human GAM precursor oligonucleotides, and 190 viral and 14,813 human GR polynucleotides, as are vectors and probes both comprising the nucleic acid molecules, and methods and systems for detecting GAM oligonucleotides and GR polynucleotides and specific functions and utilities thereof, for detecting expression of GAM oligonucleotides and GR polynucleotides, and for selectively enhancing and selectively inhibiting translation of the respective target genes thereof.

Introducing blocks of foreign genes in a single operon would avoid complications such as position effect and gene silencing inherent in putting one gene at a time into random locations in the nuclear genome. Cloning several genes into a single T-DNA does not avoid the compounded variable expression problem encountered in nuclear transgenic plants. This disclosure shows that a bacterial operon can be expressed in a single integration event as opposed to multiple events requiring several years to accomplish. Expression of multiple genes via a single transformation event opens the possibility of expressing foreign pathways or pharmaceutical proteins involving multiple genes. Expressing the Cry2aA2 operon, including a putative chaperonin to aid in protein folding, in the chloroplast via a single transformation event leads to production of crystalized insecticidal proteins. Expressing the Mer operon via a single transformation event leads to a phytoremediation system
