Q. What is an illustration of gene control?

An elegant instance of gene control in bacteria is operon system. A cluster of genes which is responsible for synthesizing a particular protein is known as an operon. This cluster of genes mainly includes a promoter region, an operator gene, a regulatory gene and a number of structural genes which actually encode the protein. Operon systems can be inducible (meaning they are normally "off") or repressible (meaning they are normally "on").
