[img_assist|nid=170|title=|desc=|link=none|align=right|width=100|height=43]50 years ago the structure of DNA was determined 1 and hailed as the “secret of life”. The determination of the structure of DNA made it seem as if the complete understanding of living organisms was possible, even though fundamental questions regarding DNA function were unanswered, and remain so today. Later, in the 1970s and 1980s, the technology to insert genes at random into the genomes of organisms were developed and termed genetic engineering (GE).
