What is the biological advantage of operons to bacteria? a. promoters and repressors as parts of operons serve as information integrating units, thereby affording more flexible response to the environmental changes. b. operons provide redundancy in proofreading the most essential parts of genetic code, thereby reducing the susceptibility of the organism to lethal mutations. c. operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process. d. operons significantly increase the rate of dna replication, thereby ensuring the required rate of bacteria reproduction.
