The present invention relates to a first group of novel oligonucleotides, here identified as “Genomic Address Messenger” or “GAM” oligonucleotide, and a second group of novel operon-like 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 diseases. Nucleic acid molecules are provided respectively encoding 122,764 GAM oligonucleotides and their respective precursors, and 18602 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.
