Major

The three emphases areas within the Biochemistry major are Chemistry, Biology, and Medical Sciences. The Biology and Chemistry emphases are for students interested in postgraduate education or employment in the basic areas of the discipline of Biochemistry. The goal of the Medical Sciences emphasis is to prepare students for admission to postbaccalaureate education in the health professions. The Biology, Chemistry, and Medical Sciences emphases focus on the development of laboratory and critical thinking skills, and hands- on laboratory experience. In addition, participation in an independent research project (BCH 197) or research tutorial (BCH 190), carried out under the supervision of a faculty member, is encouraged. Internships in industry (BCH 198I) are also available, and often lead to valuable job experience and employment opportunities.

The department offers both B.A. and B.S. degrees. The major and emphasis requirements are the same for both, 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).

Note: A maximum of 12 units of 190-199 courses may be counted toward the 180 unit graduation requirement. All courses used towards the Biochemistry major requirements must be taken for letter grades.

Transfer Students

Transfer students desiring to major in Biochemistry must have completed:

  • 1. Two quarters of calculus, equivalent to

MATH 009A and MATH 009B

  • 2. A year of general chemistry, equivalent to

CHEM 001A, CHEM 01LA, CHEM 001B, CHEM 01LB, CHEM 001C, CHEM 01LC

  • 3. A year of organic chemistry, equivalent to

CHEM 008A, CHEM 08LA, CHEM 008B, CHEM 08LB, CHEM 008C, CHEM 08LC

  • 4. A course in general biology, equivalent to

BIOL 005A and BIOL 05LA

Strongly recommended but not required for admission to the major are:

and BIOL 005C

2 One quarter of Ordinary Differential Equations, equivalent to MATH 046

  • 3. General physics (calculus-based) equiva-

lent to PHYS 002A, PHYS 002B, PHYS 002C or PHYS 040A, PHYS 040B, PHYS 040C

Students must have a minimum grade point average of 2.70 in transferable college courses.

University Requirements

See Undergraduate Studies section.

College Requirements

See College of Natural and Agricultural Sciences, Colleges and Programs section.

Some of the following requirements for the major may also fulfill some of the college’s breadth requirements. Consult with a department advisor for course planning.

Major Requirements

The major requirements and the emphasis requirements are the same for the B.A. and the B.S. degree in Biochemistry. Choose one emphasis.

Continuation in the major requires that the stu- dent maintains cumulative and upper division/ science GPAs of 2.00 or higher, a GPA of 2.00 or higher in each academic quarter, and makes ad- equate progress in the major with no more than 16 units of repeated courses. Adequate progress in the major is defined as (a) earning no grade lower than a “C-” in any required lower division mathematics or science course, STAT 010, CHEM 008A, CHEM 08LA, CHEM 008B, CHEM 08LB, CHEM 008C, CHEM 08LC, or any upper division BCH course, and (b) completing MATH 007B or MATH 009B and CHEM 001A by the end of the Fall Quarter of the second year of residence and BCH 110A or BCH 110HA, and BCH 110B or BCH 110HB, by the end of the third year of residence. Fresh- men must also complete BCH 095 with a grade of “S” during their first year of residence. BCH 095 may be waived for transfer students and students who change their major after their first year. Freshmen in the Medical Science Emphasis must also complete BCH 096 with a grade of “S” during their first year of residence. BCH 096 may be waived for transfer students and students who change their major after their first year. A student who does not meet these adequate progress standards will be discontinued from the major. In addition, a student who receives a grade of “D+” or lower in any two of the courses in (A) on the first attempt, or in any one of these courses in each of two attempts, will be discontinued from the major. Students who receive a grade lower than “B-” in BIOL 005A or CHEM 008A are strongly encouraged to complete BCH 100 during their second year of residence to better prepare themselves for BCH 110A or BCH 110HA, BCH 110B or BCH 110HB, and BCH 110C or BCH 110HC.

Admission Students who have completed a bachelor’s degree in physical, biological, chemical, or agricultural sciences are invited to apply to the program. Regardless of the area of their major for the baccalaureate degree, students should have taken the following courses prior to be- ginning graduate study in biochemistry or plan to make up deficiencies soon after entering graduate school:

  • 1. One year of calculus
  • 2. One year of general physics
  • 3. One year of organic chemistry
  • 4. An introductory course in physical chemistry
  • 5. At least two courses in biology at the

upper-division level, including genetics

Doctoral Degree

The Department of Biochemistry offers the Ph.D. degree in Biochemistry and Molecular Biology.

Course Work The following courses are required. Credit for upper division courses listed below will be given at the discretion of the graduate advisor if equiv- alent coursework has been taken previously. Students’ course requirements are determined in consultation with the graduate advisor for them upon their arrival. The graduate advisor suggests an individualized course program involving classes in biochemistry and subsidiary fields of study, 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.

BCH 110A-110B-110C: General Biochemistry

BCH 162; or equivalent research experience

BCH 184: Topics in Physical Biochemistry

BCH 210; Biochemistry of Macromolecules

BCH 211; Molecular Biology

BCH 212; Signal Transduction.

BCH 230 series: at least one course

BCH 240 Special topics in Biochemistry; required each quarter from the time the student finds a permanent major professor. The course consists of the laboratory group meeting of the student’s Major Professor

BCH 250 Oral Presentation in Biochemistry; this course must be taken prior to Advance- ment to Candidacy.

BCH 251 Graduate Seminar in Biochemistry; one formal oral presentation is required in the student’s first four years in the program.

BCH 252 General Seminar in Biochemistry; must be taken every quarter, when offered except when they present in the seminar, they must enroll in BCH 251 instead. Excep- tions to this rule may be made by petition to the Graduate Advisor in cases where the General Seminar in Biochemistry conflicts with the student’s Teaching Assistant re- sponsibilities

GDIV 403 Interdisciplinary Seminar: Research and Scholarship Ethics; must be taken once within one year of advancement to candidacy.

Elective Course Requirement: The elective courses consist of at least 9 units of graduate or upper division undergraduate course work in the sciences. Courses taken to satisfy deficien- cies at the time of admission cannot be count- ed toward the elective course requirements.

At the end of the second quarter, students se- lect major professors and are ready to initiate a research project. At the end of the first year, students submit a written report describing their research efforts and relating them to current biochemical work in related areas.

Written and Oral Qualifying Examinations At the end of the first year, and no later than the end of the second year, students take a comprehensive written qualifying examination consisting of material from BCH 210, BCH 211, and BCH 212.

Upon successful completion of this exam, the student will 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 requirement for an oral qualifying examination. Students completing all necessary requirements are advanced to candidacy for the Ph.D. degree.

Students must sit the comprehensive written exam within the first two years in the pro- gram. Unless excused by either the graduate advisor or department chair, failure to sit the examination will be regarded as a failed exam. Students must sit every sequential offering of the exam and no student will be given more than two attempts to achieve a satisfactory grade on the comprehensive written exam.

The Oral Qualifying Exam can be taken in one of the following modes: In-Person or Hybrid. The student and their advisor will discuss which mode best suits the subject matter, with the advisor making the final determination. Students taking the exam In-Person are expected to present on campus with all committee members physically present. If Hybrid is chosen, the student is expected to present the exam on campus in a video enabled room that supports some members physically present and others remote.

Dissertation and Final Oral Examination Following completion of their research, students submit a written dissertation and conclude their studies with an oral defense of the dissertation.

The Final Defense can be taken in one of the following modes: In-Person or Hybrid. The student and their advisor will discuss which mode best suits the subject matter, with the advisor making the final determination. Stu- dents presenting the Final Defense In-Person are expected to present on campus with all committee members physically present. If Hybrid is chosen, the student is expected to present the Final Defense on campus in a video enabled room that supports some mem- bers physically present and others remote.

Teaching Requirement As part of the program,each student is required to serve at least two quarters as a teaching assistant.

Professional Development Training Ph.D. graduate students fulfill their profession- al training requirement through enrollment in BCH 250, BCH 252 and GDIV 403.

Normative Time to Degree 15 quarters. In the case that a student changes the degree aim from M.S. to Ph.D., normative time will be reset.

Master’s Degree

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

Course Work The following courses offered by the Biochem- istry Department, or acceptable substitutes (determined by the Graduate Advisor when the student joins the program), are required:

BCH 110A-110B-110C: General Biochemistry

BCH 162;or equivalent research experience

BCH 184: Topics in Physical Biochemistry

BCH 210; Biochemistry of Macromolecules
