Overview

    The bachelor of science in biochemistry is designed to provide students with a thorough foundation in chemistry and biology and an appreciation of how these sciences are integrated to explore the molecular mechanisms underlying biological processes. The plan of study prepares students for careers in medicine, veterinary medicine, biomedical research, agriculture, industrial biochemistry, or biotechnology. In addition, it provides the background for post-graduate studies in the life sciences or professional studies in medicine, nursing, veterinary medicine, dentistry, pharmacy, and clinical chemistry.

    The department offers the undergraduate biochemistry degree in two colleges, the College of Agriculture and Life Sciences and the College of Science. Biochemistry majors complete the Curriculum for Liberal Education requirements unique to the college in which they are enrolled.

    The departmental requirements for majors in either college are: mathematics (9-12 credits); physics (8 credits); principles of biology (8 credits); genetics (3 credits); general microbiology (4 credits); general chemistry (8 credits); organic chemistry (8 credits); physical chemistry (6 credits); analytical chemistry (4 credits); introduction to biochemistry (1 credit); organic biochemistry (1 credit); general biochemistry (7 credits); and laboratory problems in biochemistry and molecular biology (6 credits).

    To qualify for a major in biochemistry, the department requires that students maintain a minimum 2.0 grade point average (GPA) for the hours passed in all required biochemistry, biology, and chemistry courses. In addition, the department requires that a student earn a C- or better in all required biochemistry, chemistry, and biology courses.

    The plan of study allows time for qualified students to participate in undergraduate research (BCHM 4994). Qualified students are strongly encouraged to initiate research activity prior to their senior year. A minimum GPA of 2.5 is required for enrollment in BCHM 4994. Students participating in undergraduate research are encouraged to present a senior thesis.

    Upper-division students who qualify for the Honors Program may participate in the "in honors" degree program in biochemistry. The Honors Program and undergraduate research program include study and research with individual faculty members.

    Biochemistry majors may participate in the Cooperative Education Program that alternates academic study with employment experience. Additional information pertaining to the CO-OP program is included in the "General Information" section of this catalog. Summer internships with various businesses and governmental agencies are frequently available, particularly to rising seniors.

Biotechnology Option

    Biotechnology is the application of fundamental biochemical and molecular biological approaches to problems in agriculture, medicine, biotechnology, energy, and environmental sciences. The faculty in biochemistry and in several other science departments have developed an interdisciplinary option for undergraduates. To complete the option, Biochemistry majors must also take BCHM 4784 (Biotechnology Applications) and will graduate with a degree in biochemistry with an option in biotechnology. The option will introduce information, concepts, and techniques that are shaping the future of science and our society.

Bioinformatics/Genomics

    The department supports students' interest in bioinformatics/genomics by providing instruction and laboratory experience in those areas. Students are advised of appropriate supporting courses in computer science that may be used toward a minor in Computer Science.

    The department also offers graduate programs leading to the M.S. and Ph.D.

    The minimum number of credits required for the B.S. in Biochemistry is 120.
