(i) Mention the difference in the mode of action of exonuclease and endonuclease.
(ii) How does restriction endonuclease function?
(i) Exonucleases cleave base pairs of DNA at their , terminal ends (either 5’ or 3 0 while, the endonucleases cleave DNA at any point within DNA segment at specific position except terminal ends.
(ii) Restriction endonuclease EcoRI cuts the DNA strands a little away from the palindromic sequences, but between the same two bases on the two strands
