Abstract
The invention concerns a method for extending the half-life of mRNAs. The half-life extension is conferred upon the mRNA by a co-transcribed positive retroregulatory element which is ligated to the 3' end of the DNA sequence encoding the RNA. RNAs having an extended half-life conferred by a co-transcribed positive retroregulatory element are also claimed.
