Operon Concept
The operon concept proposed by Jacob and Monod is applicable to all prokaryotes and all eukaryotes.
Explanation
- The operon concept is a model for gene regulation in prokaryotes where multiple genes are controlled by a single promoter and operator. This includes genes involved in the same metabolic pathway or cellular function.
- In prokaryotes, such as Escherichia coli, the lac operon is a classic example of gene regulation. It consists of three structural genes (lacZ, lacY, and lacA) involved in lactose metabolism, as well as regulatory elements like the promoter and operator.
- In eukaryotes, although the organization of genes is more complex compared to prokaryotes, similar regulatory mechanisms exist. For example, in eukaryotic cells, genes can be co-regulated by enhancers and silencers, similar to the operator in prokaryotic operons.
- The operon concept highlights the coordinated regulation of gene expression to ensure efficient use of cellular resources. It allows for the simultaneous control of multiple genes involved in a common pathway or function.
- While the specific regulatory mechanisms and components may differ between prokaryotes and eukaryotes, the fundamental principles of gene regulation proposed by the operon concept apply to both types of organisms.
Therefore, the operon concept is applicable to all prokaryotes and all eukaryotes, making option 'C' the correct answer.
