Abstract
Regulation of eucaryotic gene expression is controlled by procaryotic peptides. The peptides recognize specific DNA sequences present in the gene, which may be derived from procaryotic genes, and either activate or repress gene transcription. Hybrid procaryotic peptides may be used containing both repressor and activator peptides.
