Question

A group of genes that are regulated together and produce a single enzyme is known as an operon. In operons, the genes are transcribed together in a single mRNA molecule, and mutations in any of the genes can affect the production of the final enzyme product. Therefore, if one of these genes is mutated and the enzyme is no longer produced, it must be part of an operon.
