Description: This U.S. industry comprises establishments primarily engaged in conducting biotechnology (except nanobiotechnology) research and experimental development. Biotechnology (except nanobiotechnology) research and experimental development involves the study of the use of microorganisms and cellular and biomolecular processes to develop or alter living or non-living materials. This research and development in biotechnology (except nanobiotechnology) may result in development of new biotechnology (except nanobiotechnology) processes or in prototypes of new or genetically-altered products that may be reproduced, utilized, or implemented by various industries. Illustrative Examples: Cloning research and experimental development laboratories DNA technologies (e.g., microarrays) research and experimental development laboratories Nucleic acid chemistry research and experimental development laboratories Protein engineering research and experimental development laboratories Recombinant DNA research and experimental development laboratories Cross-References.
