Vedclass · Answer

(A) The operon model,proposed by Jacob and Monod,describes a coordinated unit of gene expression in bacteria. It consists of a set of structural genes,an operator,and a promoter. This mechanism of gene regulation is a fundamental characteristic of prokaryotic organisms. While some operon-like structures (such as polycistronic transcription) have been identified in certain eukaryotes (like $C. elegans$),the classic operon model is primarily and universally applicable to all prokaryotes.

Jacob and Monod studied lactose metabolism in $E. coli$ and proposed the operon concept. The operon concept is applicable to:
