Question

In the diagram showing the gene structure, what is labeled "UTR"?

• A. 5' UTR, 3' UTR
• B. 5' UTR, 3' UTR
• C. Exons and Introns
• D. Both 5' and 3' UTR

Hint:

The 5' and 3' UTRs are essential for translation regulation, stability, and proper mRNA processing.

Answer 1

The Correct Option is B

Step 1: Understanding the Question.
This question asks about the diagram showing the gene structure and the term "UTR."

Step 2: Analyzing the Options.
(A) 5' UTR, 3' UTR: Correct — The UTRs are untranslated regions at the 5' and 3' ends of the mRNA transcript.
(B) 5' UTR, 3' UTR: This is the same as option A.
(C) Exons and Introns: These are parts of the gene, but they are not the untranslated regions.
(D) Both 5' and 3' UTR: This is a repeat of (A), but correctly represents both regions.

Step 3: Conclusion.
The correct answer is (B) 5' UTR, 3' UTR, as these are the regions present in the mRNA transcript.
