Repressors and activators are proteins produced in the cell. Both repressors and activators regulate gene expression by binding to specific DNA sites adjacent to the genes they control.Therefore, in prokaryotic cells, the control of gene expression is almost entirely at the transcriptional level. Eukaryotic cells, in contrast, have intracellular organelles and are much more complex. Recall that in eukaryotic cells, the DNA is contained inside the cell’s nucleus and that is where it is transcribed to produce mRNA.
