Regulation of gene expression by employing translational inhibition of MRNA utilizing interfering complementary MRNA
First Claim
Patent Images
1. A prokaryotic or eukaryotic cell containing a non-native DNA construct, which construct produces an RNA which regulates the function of a gene, said DNA construct containing the following operably linked DNA segments:
- a. a transcriptional promoter segment;
b. a transcription termination segment; and
therebetweenc. a DNA segment;
whereby transcription of the DNA segment produces a ribonucleotide sequence which does not naturally occur in the cell, is complementary to a ribonucleotide sequence transcribed from said gene, and said non-naturally occurring ribonucleotide sequence regulates the function of said gene.

Abstract
Gene expression in a cell can be regulated or inhibited by incorporating into or associating with the genetic material of the cell a non-native nucleic acid sequence which is transcribed to produce an mRNA which is complementary to and capable of binding to the mRNA produced by the genetic material of said cell.
