Recombinant DNA molecule can be created normally by cutting the vector DNA and source DNA respectively with:
  1. Hind II, Hind II
  2. Hind II, Alu I
  3. Hind II, EcoR I
  4. Hind II, BamHI

Solution

Option (1) is the correct answer because, unless we cut the vector and the source DNA with the same restriction enzyme, the recombinant vector molecule cannot be created. In options (2), (3) and (4), restriction enzymes are different for cutting the vector DNA and source DNA, so they cannot be the answers.
