Biotechnology has been described as"Janus-faced"This implies that there are two sides.On one. techniques allow DNA to be manipulated to move genes from one organism to another.On the other,it involves relatively new technologies whose consequences are untested and should be met with caution.

It has brought us to the brink of a world of "engineered" products that are based in the natural world rather than on chemical and industrial processes. Biotechnology has been described as "Janus-faced." This implies that there are two sides. On one, techniques allow DNA to be manipulated to move genes from one organism to another. On the other, it involves relatively new technologies whose consequences are untested and should be met with caution. The term "biotechnology" was coined in 1919 by Karl Ereky, an Hungarian engineer. At that time, the term meant all the lines of work by which products are produced from raw materials with the aid of living organisms. Ereky envisioned a biochemical age similar to the stone and iron ages. A common misconception among teachers is the thought that biotechnology includes only DNA and genetic engineering.
