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.
