According to Jacob and Monod ... Prokaryotic cells must have the opportunity to control protein biosynthesis for a more ecological use of energy. Otherwise, either too many or too few proteins would be formed. Jacob (* 1920) and Monod (1910-1976) researched E. coli bacteria and found gene regulation through substrate induction and end-product repression.
