Question

Match the RNAs in Group I with their corresponding function in Group II 
Group I               Group II 
(P) snRNA          (1) rRNA processing 
(Q) piRNA          (2) RNA splicing 
(R) snoRNA        (3) Selected mRNAs degradation 
(S) siRNA            (4) Germ line protection from transposable elements 
 

• A. P-4, Q-3, R-1, S-2
• B. P-4, Q-1, R-3, S-2
• C. P-3, Q-2, R-1, S-4
• D. P-2, Q-4, R-1, S-3

Hint:

Different types of small RNAs have specific functions in RNA processing, mRNA degradation, and protection from transposable elements.

Answer 1

The Correct Option is D

Step 1: Understanding the functions of RNAs. 
- snRNA is involved in RNA splicing (P-2). 

- piRNA is involved in germline protection from transposable elements (Q-4). 

- snoRNA is involved in rRNA processing (R-1). 

- siRNA is involved in selected mRNA degradation (S-3). 
 

Step 2: Analyzing the options. 
(A) P-4, Q-3, R-1, S-2: Incorrect — Some pairings are incorrect. 
(B) P-4, Q-1, R-3, S-2: Correct — Some pairings are incorrect. This pairing correctly matches the RNA types with their functions. 
(C) P-3, Q-2, R-1, S-4: Incorrect — Some pairings are incorrect. 
(D) P-2, Q-4, R-1, S-3: Incorrect — This pairing correctly matches the RNA types with their functions. 
 

Step 3: Conclusion. 
The correct answer is (D) P-2, Q-4, R-1, S-3
