Which of the following restriction enzymes produces blunt ends?
Correct answer: B. EcoRV
- A. Sal I
- B. EcoRV
- C. Xho I
- D. Hind III
Explanation
EcoRV is a type II restriction endonuclease isolated from certain strains of E.coli. It creates blunt ends. It recognizes the palindromic sequence of 6 bases as shown here:SalI, XhoI and HindIII restriction enzymes produce sticky ends.
