Can eukaryotes have operons

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. WebWith a few exceptions (C. elegans and related nematodes), eukaryotic genomes do not have genes arranged in operons.Instead, eukaryotic genes that are co-regulated tend to have the same DNA regulatory element sequence associated with each gene, even if those genes are located on completely different chromosomes.
