Study Notes
Restriction Enzymes
- Discovered in 1963, restriction enzymes were the first tools used in genetic engineering
- Restriction enzymes cut DNA at specific sequences called recognition sequences
- Restriction endonuclease Hind II was the first enzyme to be identified
- Hind II recognizes six base pairs in a DNA sequence
- There are over 900 known restriction enzymes, isolated from over 230 bacteria strains
- The naming convention of restriction enzymes names them after their genus and species of origin - for example, EcoRI was isolated from Escherichia coli RY13
