Understanding the molecular workings of cells is being transferred into rapid advances in medicine and agriculture. These advances have spawned a new biotechnology industry, allowing the introduction of beneficial genes into crop plants and domestic animals, and promising to lessen the severity of certain genetic diseases. Majors study fundamental biological questions about gene and cell structure and function. Students are encouraged to participate in active research with professors. Possible careers include medicine, industry, education or emerging fields in biotechnology.
