Assertion :- Gene regulation in prokaryotes is comparatively simple than eukaryotes.
Reason : In most of prokaryotic operons the genes present in the operon are needed together to function in the same or related metabolic pathway.

A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.

B

The correct Answer is:
To solve the assertion and reason question, let's break it down step by step: ### Step 1: Analyze the Assertion - **Assertion:** "Gene regulation in prokaryotes is comparatively simpler than in eukaryotes." - **Analysis:** This statement is true. Gene regulation in prokaryotes is indeed simpler because it primarily occurs at the transcriptional level, often at the promoter region. Prokaryotes typically have operons, which are clusters of genes transcribed together, making regulation straightforward. ### Step 2: Analyze the Reason - **Reason:** "In most of prokaryotic operons, the genes present in the operon are needed together to function in the same or related metabolic pathway." - **Analysis:** This statement is also true. In prokaryotic operons, such as the lac operon, the genes are organized in a way that they encode proteins that work together in a specific metabolic pathway. For example, the lac operon contains genes that are all involved in the metabolism of lactose. ### Step 3: Determine the Relationship - Since both the assertion and reason are true, we need to assess if the reason correctly explains the assertion. - The reason does explain why gene regulation in prokaryotes is simpler: because the genes are organized to work together in metabolic pathways, making the regulation more efficient and straightforward. ### Conclusion - Both the assertion and reason are true, and the reason is the correct explanation of the assertion. Therefore, the answer is that both statements are true, and the reason is the correct explanation of the assertion. ### Final Answer - **Both Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.** ---
