Operon process is held in bacteria for to digest the lactogen. And it has a closely linked genes.The genes are (X,Y,Z).we can assume like this. These Three gene play a drementous role in digesting the lactogen.Whenever a lactogen was present , this process get ON.
so option (B) is correct

Operon
Operon is a set of closely placed genes regulating a metabolic pathway in prokaryotes. It consists of multiple genes that work together to control the expression of a group of related genes. Here is a breakdown of the key characteristics of an operon:
Regulation of Metabolic Pathway
- Operons are responsible for coordinating the expression of genes involved in a specific metabolic pathway.
- They control the production of enzymes and other proteins necessary for carrying out a particular biochemical process.
Closely Placed Genes
- The genes within an operon are physically close to each other on the DNA molecule.
- This organization allows for coordinated regulation of gene expression, as they are transcribed together as a single unit.
Control of Gene Expression
- Operons contain regulatory elements that can switch on or off the transcription of the genes within the operon.
- This regulation ensures that the genes are only expressed when needed, in response to specific environmental signals or cellular conditions.
Prokaryotic Organisms
- Operons are mainly found in prokaryotic organisms such as bacteria.
- They are a common mechanism for efficient gene regulation in these simple organisms.
In conclusion, operons play a crucial role in coordinating the expression of genes involved in metabolic pathways in prokaryotic organisms. They provide a compact and efficient way to regulate gene expression in response to changing conditions, ensuring that the right genes are expressed at the right time.
