Question

Difference between restriction endonuclease and exonuclease

Answer 1

Endonuclease. Endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain. ... Restrictionenzymes are endonucleases from eubacteria and archaea that recognize a specific DNA sequence. The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site.
