This is known as the Central Dogma of Life, calculate, and to propose a method how DNA is replicated in cell division. These researchers proposed that production of the enzyme is controlled by an "operon, " which consists a series of related genes on the chromosome consisting of an operator, a promoter, a regulator gene, and structural genes.
