Endonucleases

Endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain.  Some, such as deoxyribonuclease I, cut DNA relatively nonspecifically, others, typically called restriction endonucleases or restriction enzymes, cleave only at very specific nucleotide sequences.  Endonucleases differ from exonucleases, which cleave the ends of recognition sequences instead of the middle (endo) portion.
