what is biotechnology
What Is Biotechnology?
  • Using scientific methods with organisms to produce new products or new forms of organisms
  • Any technique that uses living organisms or substances from those organisms to make or modify a product, to improve plants or animals, or to develop microorganisms for specific uses
