For example, much of the denim produced in the United States is finished using biotechnology enzymes. DNA fingerprinting, a biotech process, has dramatically improved criminal investigation and forensic medicine, as well as afforded significant advances in anthropology and wildlife management. There are 1,283 biotechnology companies in the United States. Approximately one-third of biotech companies employ fewer than 50 employees. More than two-thirds employ fewer than 135 people.
Biotechnology is one of the most research-intensive industries in the world.
