Transgenic: Definition

  • Genetic engineering is a term usually used to refer to the manipulation of the DNA sequences of an organism

  • Scientists have been able to artificially change an organism's DNA by combining lengths of DNA from different sources

  • The altered DNA is called recombinant DNA (rDNA)

  • Transgenic means the transfer of genetic material from one species to a different species

    • If an organism contains DNA from a different species it is called a transgenic organism

  • Any organism that has introduced genetic material is a genetically modified organism (GMO)
