Regulation of Gene Action or Genetic Control of Gene Action
DNA molecule has genetic informations for almost all the proteins which may be required by an organism, in specific amounts at certain definite times of the life cycle. But all the genes (cistrons) of DNA molecule cannot make polypeptides all the times, because there are many evidences which show that many proteins which play an important role in an adult animal are not synthesized during embryonic development and certain other proteins may be synthesized primarily during embryonic development but not during adulthood. Therefore the flow of information from DNA (gene) to protein is regulated in some manner.
