Question

What is the biological advantage of operons to bacteria?

A.)Operons significantly increase the rate of DNA replication, thereby ensuring the required rate of bacteria reproduction. B.)Operons provide redundancy in proofreading the most essential parts of genetic code, thereby reducing the susceptibility of the organism to lethal mutations. C.)Promoters and repressors as parts of operons serve as information integrating units, thereby affording more flexible response to the environmental changes. D.)Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.

Explanation / Answer

D.)Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.

The genes that correspond to a specific metabolic process are generally under the control of a single promoter, in bacteira. This is called the operon, which helps in regulation of expression of genes involved in the same metabolic process.
