Web• Eukaryotic genes are not organized into operons. • Eukaryotic regulatory genes are not usually linked to the genes they regulate. • Some of the regulatory proteins must ultimately be compartmentalized to the nucleus, even when signaling begins at the cell membrane or in the cytoplasm. • Eukaryotic DNA is wrapped around nucleosomes WebTo understand how gene expression is regulated, we must first understand how a gene becomes a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different fashions. Because prokaryotic organisms lack a cell nucleus, the processes of transcription and translation occur almost simultaneously.
