Eukaryotic genes are organized into operons

WebHumans and other eukaryotes are complex: we're made up of trillions of cells organized into unique tissues and body structures. Each cell in your body must run its own "program" of gene expression. Turning genes on in specific body parts Some genes need to be expressed in more than one body part or type of cell.

WebOperons in Eukaryotes As noted earlier, an operon is a cluster of genes transcribed from the same promoter to give a single mRNA carrying multiple coding sequences (polycistronic mRNA). However, eukaryotes only translate the first coding sequence on an mRNA. Therefore, eukaryotes cannot use polycistronic mRNA to express multiple genes. 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 ...
