Which of the following are correct about EcoRI? A. Cut the DNA with blunt end B. Cut the DNA with sticky end C. Recognise a specific palindromic sequence D. Cut the DNA between the base G and A when encounters the DNA sequence 'GAATTC' E. Exonuclease. Choose the correct answer from the options given below:EcoRI is a restriction endonuclease that recognises the specific palindromic sequence GAATTC (C) and cuts the DNA strand between the G and A bases (D), producing sticky/cohesive ends (B), not blunt ends (A is incorrect). It is an endonuclease, not an exonuclease (E is incorrect). So the correct statements are B, C and D only.
