An operon is a cluster of genes under the control of a single promoter, which enables the coordinated expression of genes involved in a related function, typically found in prokaryotic organisms. This arrangement allows for efficient regulation of gene expression in response to environmental changes, optimizing protein synthesis and translation processes. Operons are essential for cellular adaptability and play a significant role in how cells respond to various stimuli, ensuring that proteins are produced when needed and in the appropriate amounts.
