Restriction endonucleases (restriction enzymes) recognize specific palindromic DNA sequences and cleave the phosphodiester bonds, producing sticky or blunt ends. They are essential tools for recombinant DNA technology. DNA polymerase synthesizes DNA, ligase joins fragments, helicase unwinds. Examples: EcoRI, HindIII. These enzymes are naturally present in bacteria as a defense against viruses.
