The aim of genetic engineering is to remove a gene (or genes) from one organism and trasfer it into another so that the gene is expressed in its new host

The DNA that has been altered by this process and which now contains lengths of nucleotides from two different organisms is called recombinant DNA (rDNA)

The organism which now expresses the new gene or genes is known as a trangenic organism or a genettically modified organism (GMO)

Recombinant DNA - DNA made by joining pieces from two or more different sources

  • genetic engineering provides a way of overcoming barriers to gene transfer between species
  • unlike selective breeding, where…
