Answer

  1. Recombinant DNA Technology/ Genetic Engineering.
  2. Three steps are:
  • Isolation of human DNA with desirable gene.
  • DNA segment is incorporated into bacterial plasmid to form recombinant DNA.
  • Recombinant DNA is introduced in bacterial cell, which makes pistein directed by human DNA.
