Endonuclease - Common Endonucleases

Common Endonucleases

Restriction endonucleases (ENases) are most commonly produced by bacteria, and can be used to map a piece of DNA. ENases are widespread amongst prokaryotes (bacteria and archaea), but are produced by some eukaryotic organisms as well, although this is very rare.. Some endonucleases have actions on RNA, such as the Dicer enzyme, which initiates the formation of RNA-induced silencing complexes.
