Questions and Answers

What is the purpose of using restriction enzymes (REs) in genetic engineering?

  • To generate maps of DNA sequences
  • To generate recombinant DNA (rDNA)
  • To sequence entire genomes
  • To cut and splice DNA fragments (correct)

What are recombinant DNA (rDNA)?

  • DNA molecules that have been sequenced
  • DNA molecules that have been cut with REs
  • DNA molecules from different sources joined together (correct)
  • DNA molecules from the same source joined together

What is the function of DNA ligase enzyme in genetic engineering?

  • To sequence entire genomes
  • To generate recombinant DNA (rDNA)
  • To cut and splice DNA fragments
