Restriction enzyme. A restriction enzyme or restriction endonuclease is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites.
The animation below tells you that restriction endonucleases are very useful to molecular biologists. They cut DNA at specific locations and can be used to look for genetic diversity, to cut up DNA into smaller pieces, and/or to splice DNA from different sources into one molecule.In cells restriction endonucleases are used to cut up invading DNA from viruses. The restriction sites are ones found in viral DNA.he animation below tells you that restriction endonucleases are very useful to molecular biologists.
