Which of the following statements is not correct regarding EcoRI restriction endonuclease enzyme?

Options

  1. AIt is isolated from Escherichia coli RY13.
  2. BIts recognition sequence is 5^ -GAATTC- 3 ' 3'-CTTAAG-5'.
  3. CIt produces complementary blunt ends.
  4. DNone of these

Correct answer

C. It produces complementary blunt ends.

Step-by-step solution

The restriction endonuclease enzyme EcoRI was isolated from bacterium Escherichia coli RY13. It recognises the base sequence GAATTC in DNA duplex and cuts its strands between G and A as shown below: It results in complementary sticky ends.
