1. A-factor
A protein which is found in the bacterial genus Streptomyces that helps start the production of streptomycin and the process of morphological differentiation. It is used in biotechnology to induce these functions in mutant strains of Streptomyces that can't produce it themselves.

2. Biotechnical
Having to do with biotechnology , or applying its techniques and principles.

3. Biotechnology
The industrial use of living organisms or biological techniques developed through basic research. biotechnology products include antibiotic s, insulin , interferon , recombinant DNA , and techniques such as waste recycling. Much older forms of biotechnology include bread making, cheese making and brewing wine and beer.

4. Chlamydomonas
A genus of green algae consisting of more than 600 species worldwide, living in marine, freshwater, soil, and even snow environments. They are single cell ed eukaryotic organisms ranging from 5 to 100 micrometers long which can be roughly spherical, egg shaped, or elliptical. Most species have two flagella (coming out the same side) for swimming. Most of the time they are haploid and reproduce by dividing into two ( binary fission ); when they are stressed they can form gamete s which fuse to form diploid cyst s which later divide into four haploid cells. Taxonomically they have been classified under plants, animals, and protist s. Several species from this genus are important model organisms for the study of cell biology , molecular biology , genetics , plant physiology , and biotechnology . The species most commonly used in scientific experiments is Chlamydomonas reinhardtii (also known as C. reinhardi or C. reinhardii).

5. Environmental Protection Agency (EPA)
The U.S. regulatory agency for biotechnology of microbes. The major laws under which the agency has regulatory powers are the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA); and the Toxic Substances Control Act (TSCA).

6. Food and Drug Administration (FDA)
The U.S. agency responsible for regulation of biotechnology food products. The major laws under which the agency has regulatory powers include the Food, Drug, and Cosmetic Act; and the Public Health Service Act.

7. Mycoplasmas
Very tiny microorganisms (usually spherical with a diameter of .3 to .8 micrometers, the smallest cells known) which are able to slip through most filters and are therefore often found as contaminating organisms in cultures, vaccines and other supposedly sterile preparations. Some types of mycoplasmas cause pneumonia. Mycoplasmal contamination is an important problem in biotechnology , but fortunately the microbes can usually be killed with antibiotic s.

8. National Science Foundation (NSF)
A nonregulatory U.S. federal agency which has oversight of biotechnology research activities that the agency funds.

9. Neoplastic transformation
Neoplastic transformation is the conversion of normal cells into tumor cells. Frequently this is the result of a genetic change ( mutagenesis ) and the same term is used to describe the genetic modification of bacteria for use in biotechnology. See epigenetic change s, genetic toxicology , genotoxic , mutation , mutagenesis , tumor .

10. Occupational Safety and Health Administration (OSHA)
One of the U.S. agencies responsible for regulation of biotechnology . The major law under which the agency has regulatory powers is the Occupational Safety and Health Act.
