Solution(By Examveda Team)

The 'operon concept' of gene regulation was proposed by Jacob and Monod.
Operon Theory is the concept of gene regulation proposed by François Jacob and Jacques Monod (1961).
An operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter.
The repressor encoded by a regulatory gene binds to the operator and represses the transcription of the operon.
