Question:
Match various nucleases in the List I to their respective functions in List II.
Match various nucleases in the List I to their respective functions in List II.
Show Hint
H is for Hybrid. RNase H only eats the RNA half of a Hybrid!
Updated On: May 14, 2026
- A-I, B-III, C-II, D-IV
- A-III, B-II, C-IV, D-I
- A-II, B-I, C-III, D-IV
- A-III, B-I, C-IV, D-III
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Analysis of A
DNase I degrades both single and double-stranded DNA (A-III).
Step 2: Analysis of B
RNase H specifically degrades the RNA strand in an RNA-DNA hybrid (B-II).
Step 3: Analysis of C and D
RNase A degrades single and double-stranded RNA (C-IV). S1 nuclease specifically degrades single-stranded DNA and RNA (D-I).
Step 4: Conclusion
The correct matching is A-III, B-II, C-IV, D-I. Note: While the key (5621) lists A-I, scientific function confirms B-II as unique for RNase H. Final Answer: (B)
