Question

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.

Answer 1

The correct answer is option C, that is, the Operons afford the organism the opportunity to simultaneously monitor the transcription of multiple genes, whose products are active in the same process.  

The genes, which correspond to a particular metabolic procedure are usually under the control of a single promoter in a bacteria. This is known as Operon that assists in monitoring the expression of genes taking part in the similar metabolic procedure.
