MAJOR  

Biochemistry holds a central position in the life sciences. At the interface between Biology and Chemistry, it deals with the molecular structures and reactions essential to all life processes. A degree in Biochemistry prepares students for a broad range of career possibilities in research, industry, and the health professions. In the past decade, a third of our graduates have entered professional schools (medical, dental, optometry, pharmacy, osteopathy, and veterinary), a third have entered M.S. or Ph.D. graduate programs (in Biochemistry, Physiology, Public Health, Pathology, Molecular Biology, and Virology), and a third have gone to work (in the pharmaceutical and biotechnology industries, clinical and research laboratories, and teaching).

The course work required for the Biochemistry degree is rigorous and comprehensive, and gives students a solid grounding on which to base their career goals. There are two emphasis areas within the Biochemistry major, Chemistry and Biology. The choice of emphasis depends on the career plans of the student, and determines from which course groupings upper-division electives are selected to complete the major requirements. The Biology emphasis is geared toward students interested in the health professions, while the Chemistry emphasis is generally chosen by students interested in pharmacy, forensics, or biophysical sciences. In addition, the program focuses on the development of laboratory and critical thinking skills, and hands-on laboratory experience. An independent research project (BCH 197) or research tutorial (BCH 190), carried out under the supervision of a faculty member, is required for the degree. Internships in industry (BCH 198-I) are also available, and often lead to valuable job experience and employment opportunities.

The department offers degrees of both Bachelor of Arts and Bachelor of Science. The major and emphasis requirements are the same for both degrees, and most students choose the B.S. degree. The B.A. degree requires 12 additional units of Humanities and Social Sciences courses, and 16 units or a course 4 equivalency level of a foreign language (see College Breadth Requirements).

DEGREE REQUIREMENTS  

UNIVERSITY REQUIREMENTS

General University requirements are Universitywide requirements which all undergraduates must satisfy. See the Undergraduate Studies section for a complete listing.

COLLEGE REQUIREMENTS

SAMPLE PROGRAMS

Two of the many possible course programs are shown below; the outlined program is applicable for both the B.A. and B.S. degree programs. ENGL 001A-ENGL 001B-ENGL 001C should be completed as early as possible in the student's career. BCH 190 (Special Studies) or BCH 197 (Research for Undergraduate Students) is completed during the junior or senior year and may be arranged through the Undergraduate Student Advisor.

GRADUATE PROGRAM  

The Department of Biochemistry offers a graduate program leading to the Master's or Ph.D. degree in biochemistry. This program emphasizes basic biochemistry with research specialization in the areas of molecular biology, metabolic biochemistry, plant biochemistry, enzyme chemistry, physical biochemistry, and biochemical endocrinology. It is designed for students who are planning a career of research and teaching in biochemistry at colleges and universities or who wish to engage in biochemical investigations of fundamental or applied nature in private, governmental or industrial laboratories.

Students who have completed a bachelor's degree in physical, biological, or agricultural sciences are eligible to enter the program. Regardless of the area of their major for the baccalaureate degree, students should have taken the following courses prior to beginning graduate study in biochemistry or should plan to make up deficiencies soon after entering graduate school: one year of calculus, one year of general physics, one year of organic chemistry, an introductory course in physical chemistry and at least two courses in biology at the upper-division level, including genetics.

Students applying to the graduate program in biochemistry should arrange to take the Graduate Record Examination General Test in time for their scores to be submitted with their application.

DOCTORAL DEGREE

Students' course requirements are determined in consultation with a three member advisory committee appointed for them upon their arrival. Based on their interests and previous training, individual course programs are suggested for students involving courses in biochemistry and courses in a subsidiary field of study. The subsidiary field may be chosen from any of the physical, biological, or agricultural sciences. Although an adequate course preparation is a requisite part of the training program, the department encourages early involvement of the students in research directed toward their dissertations.

Students who are candidates for the Ph.D. degree normally enter the graduate program in the fall quarter at the beginning of a new academic year and begin their training according to the plan suggested by their individual advisory committees. At the end of the first quarter, the students select their major professors and are ready to initiate a research project. At the end of the first year, the students submit a written report describing their research efforts and relating them to current biochemical work in related areas. After the second year, students take a comprehensive written qualifying examination, then submit and orally defend a research report in which they describe the research they have performed thus far and develop a plan for their complete dissertation research project. This fulfills the Graduate Division's requirement for an oral qualifying examination; students completing these requirements are advanced to candidacy for the Ph.D. degree. Following completion of their research, a written dissertation is submitted, and they conclude their studies with an oral defense of the dissertation. As part of the program, each student is required to serve at least two quarters as a teaching assistant.

The normative time to the Ph.D. degree is 15 quarters.

MASTER'S DEGREE

In addition to the Ph.D. program, the department offers two plans for the Master's degree (Plan I--Thesis; Plan II--Comprehensive Examination). Both plans require completion of at least 36 course units; for Plan I, a maximum of 12 units may be for thesis research.
