Biochemists and biophysicists typically do the following:
Biochemists and biophysicists use advanced technologies, such as lasers and fluorescent microscopes, to conduct scientific experiments and analysis. They also use x rays and computer modeling software to determine the three-dimensional structures of proteins and other molecules. Biochemists and biophysicists involved in biotechnology research use chemical enzymes to synthesize recombinant DNA.
Biochemists and biophysicists work in basic and applied research. Basic research is conducted without any immediately known application; the goal is to expand human knowledge. Applied research is directed toward solving a particular problem.
Biochemists involved in basic research may study the molecular mechanisms by which cells feed, divide, and grow. Others study the evolution of plants and animals, to understand how genetic traits are carried through successive generations.
Biophysicists may conduct basic research to learn how nerve cells communicate or how proteins work. Biochemists and biophysicists who conduct basic research typically must submit written grant proposals to colleges and universities, private foundations, and the federal government to get the money they need for their research.
Biochemists and biophysicists who conduct applied research attempt to develop products and processes that improve people's lives. For example, in medicine, biochemists and biophysicists develop tests used to detect infections, genetic disorders, and other diseases. They also develop new drugs and medications, such as those used to treat cancer or Alzheimer's disease.
Applied research in biochemistry and biophysics has many uses outside of medicine. In agriculture, biochemists and biophysicists research ways to genetically engineer crops so that they will be resistant to drought, disease, insects, and other afflictions. Biochemists and biophysicists also investigate alternative fuels, such as biofuels - renewable energy sources from plants. In addition, they develop ways to protect the environment and clean up pollution.
Many people with a biochemistry background become professors and teachers. For more information, see the profile on postsecondary teachers.
