Vedclass · Answer

(A) The operon model was proposed by Jacob and Monod in $1961$ to explain the regulation of gene expression and protein synthesis specifically in prokaryotes,such as $E. coli$. In this model,a cluster of genes (operon) is regulated by a single promoter and operator,allowing the cell to respond efficiently to environmental changes. While some operon-like structures exist in eukaryotes,the classic operon concept as defined by Jacob and Monod is a fundamental characteristic of prokaryotic gene regulation.

Jacob and Monod studied lactose metabolism in $E. coli$ and proposed the operon concept,which is applicable for:
