Question

Which of the following is a restriction endonuclease?

• A. DNA polymerase
• B. RNA polymerase
• C. EcoRI
• D. Ligase

Hint:

Restriction endonucleases like EcoRI are essential tools in molecular biology for cutting DNA at specific sequences, facilitating genetic cloning and analysis.

Answer 1

The Correct Option is C

EcoRI is a well-known restriction endonuclease that recognizes specific DNA sequences and cleaves the DNA at or near these sites. DNA polymerase and RNA polymerase are involved in DNA and RNA synthesis, respectively, while ligase is an enzyme that joins DNA fragments together.
