In eukaryotes most of the DNA does not code for a protein. It was once termed 'junk DNA' but we know now that it has some important regulatory functions. In eukaryotes there are no operons, each gene is transcribed …

WebIn prokaryotes, structural genes of related function are often organized together on the genome and transcribed together under the control of a single promoter. The operon’s regulatory region includes both the promoter and the operator. If a repressor binds to the operator, then the structural genes will not be transcribed.
