Study Notes
- Enzymes that cut DNA are classified into two categories, class I and class II.
- Class I enzymes cut DNA near sites that are able to recognize sequences.
- Class II enzymes cut DNA within recognized sequences.
- Enzymes that restrict DNA replication are among the most commonly used enzymes.
- These enzymes are found in both bacteria and eukaryotes.
- Enzymes of restriction are endogenously produced and do not cut DNA as part of bacterial self-protection.
- Enzymes of restriction have specific three-letter codes that indicate their origin.
- The first enzyme to be used for DNA restriction was EcoRI.
Test your knowledge of DNA restriction enzymes with this quiz. Learn about the classification, function, and origins of class I and class II enzymes, as well as their role in DNA replication and bacterial self-protection.
