Biological techniques used to enhance products

Biotechnology (sometimes shortened to "biotech") is a field of applied biology that involves the use of living organisms to enhance crops, biofuels, household products, and medical treatments.  Modern biotechnology may involve the use of genetic engineering technology to permanently alter the genetic makeup of living organisms.
