Which of the following option is correct for recombinant DNA technology

A

endonuclease enzyme removes nucleotides from the ends of DNA

B

Exonuclease enzyme removes nucleotides from site within DNA

C

Endonuclease enzyme cut long polantric DNA strand

D

Exonuclease enzyme removes nucleotides from ends of DNA

Text Solution

Verified by Experts

The correct Answer is:
