Operons operate on sections of genes. A video begins by explaining that operons are located mainly in bacteria, specifically focusing on lac operon. This lac operon, found in E.coli, breaks down lactose. It then shows how lac operon works on the genes and demonstrates how operons work on tryptophan.
