Solution

The correct option is A Alu I
  • A restriction enzyme is an enzyme that cleaves the DNA molecule at a specific site called a restriction site. It is used to cut DNA into smaller fragments.
  • Different restriction enzymes have different restrictions sites and hence cut different yet specific DNA sequences. There are two types of restriction enzymes - endonucleases and exonucleases.
  • Exonucleases cut DNA from the end while the endonucleases cut the DNA by recognizing a specific sequence of base pairs. Alu I is an exonucleases restriction enzyme that recognizes and cuts at the AG^CT site.
Thus, the correct answer is 'Alu I.'
