Genetic Modification

WHERE A GENE FROM ONE ORGANISM IS TRANFERRED TO ANOTHER

  • organism of transferred gene will produce a protein using instructions in that gene
  • possible because all organisms use the same genetic code

Stages of genetic modification:

  • gene wanted is isolated (position on source DNA is identified)
  • useful gene is replicated
  • each copied gene is joined to a vector (a carrier for the gene) ---> plasmids and viruses are often used
  • these vectors are transferred into new
