  • Recombinant DNA
  • For DNA recombination, we need first to copy it using a process called PCR
  • Then, with these copies, we need to make different combinations to have as a result a transgenic organism
  • This makes it possible to change the genetic composition of an organism
  • Recombinant DNA
  • Later, scientist started using plasmids to insert the recombinant DNA into host cells
  • This was mainly to avoid the inserted DNA to vanish. They use genetic markers to control this process.
  • Transgenic organisms can be produced by the insertion of recombinant DNA into the genome of a host
  • Transgenic plants and animals may have some special traits that make them better in most aspects
  • Genetic engineering has a lot of applications now a days
  • Some examples are genetic modified crops and animals, which often bring more benefits than the normal ones.
  • It may also be used in health with gene therapy for treating diseases
