Question:
Which one of the following is a restriction enzyme?
Which one of the following is a restriction enzyme?
Show Hint
Restriction enzymes are also called restriction endonucleases.
Updated On: Feb 4, 2026
- RNA polymerase
- DNA polymerase
- Ligase
- EcoR I
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding restriction enzymes.
Restriction enzymes are molecular scissors that cut DNA at specific recognition sequences.
Step 2: Identifying the correct option.
EcoR I is a well-known restriction endonuclease isolated from {Escherichia coli}.
Step 3: Conclusion.
Hence, the correct answer is (D) EcoR I.
