Making Multiple Copies of a Gene or DNA Segment

  • Recombinant DNA: contains DNA segments or genes from diff sources
    • One part of DNA molecule, chromosome or organism to another
  • Transfer of DNA segments can happen naturally thru viral transduction, bacterial conjugation, or transposons & regular event in eukaryotes they crossing over
  • Recombinant DNA can be produced artificially with biotechnology: use of biological systems to modify organisms or produce desired products
