Department of Biochemistry

Last updated: June 15, 2016 at 11:09 a.m.


Undergraduate Major
The Biochemistry major is designed to equip students with a broad understanding of the chemical and molecular events involved in biological processes. The Biochemistry major provides a foundation for careers in medicine, biotechnology, or research in all branches of the biological sciences.

The general aim of the major is to ensure that the students first learn the necessary chemical and physical chemical background and then the basic principles and observations of biochemistry and molecular biology. The department also offers advanced courses in more specialized subjects such as enzyme mechanisms and X-ray crystallography. These advanced courses sample the range of subjects that can be studied by biochemical methods and from a biochemical point of view.

Learning Goals

The modern discipline of biochemistry lies at the nexus of what classically have been considered the three “hard” sciences: physics, chemistry, and biology. This subject draws from physics and chemistry fundamental principles governing the behavior of molecules, and seeks to understand how these principles underlie the workings of living cells. The focus of the Brandeis biochemistry curriculum - the fulcrum around which the fundamental molecular principles are brought to bear upon life-processes - is the study of macromolecules. These huge molecular complexes - proteins, nucleic acids, and membrane assemblies - are the molecular machines that directly carry out virtually all operations of living cells: transmission of genetic information through the generations, catalysis of the chemical reactions that allow energy to flow through biological systems, generation of electricity in the nervous system, communication amongst tissues of multicellular organisms, disruption of healthy life-processes by pathogenic micro-organisms, to name a tiny fraction of the myriad examples of macromolecular function.

Two features of biochemistry as a discipline strongly influence our undergraduate curriculum. First, biochemistry is intrinsically reductionist in attitude. It finds value in studying the isolated parts of biological machines as a means of understanding those more complicated machines themselves, as well as their interactions with the cellular milieu. It asserts that macromolecules, despite their own complexity, can be understood by judicious application of physical-chemical law. Second, as a young field still exploding with new techniques and insights (rather analogous to physics in the first half of the 20th century), biochemistry is very much a moving target. While the fundamental physical-chemical principles underlying macromolecular behavior are timeless, the biochemical manifestations of these principles continue to change on the rapidly expanding edge of discovery. Our curriculum must be designed to track this change - to train students to engage with future issues in life-science that do not currently exist.

All students graduating with a Biochemistry major should have knowledge of the following general areas:

  • Basic principles of cell biology.
  • Firm understanding of general chemistry and organic chemical reaction mechanisms, particularly in the area of carbonyl chemistry.
  • Molecular forces determining protein and nucleic acid folding and membrane assembly.
  • Mechanisms by which enzymes catalyze cellular chemical reactions.
  • Strategies by which cells store and transmit information in DNA and RNA.
  • Mechanisms for communicating changes in the extracellular environment to the cell’s interior.
  • Techniques for determining molecular structures of macromolecules.
  • Relation of impairment in macromolecular function to disease.
  • All Honors majors will be additionally required to carry out an original research project in the laboratory of a Brandies life-science faculty member.

Core skills
Our curriculum requires majors to use a set of basic skills to attack problems particular to biochemistry, some of which should be mastered through prerequisites taken even before encountering our introductory course. The core skills needed for the major are:

  • Facility with familiar mathematical functions, proficiency in univariate calculus, and understanding of basic elements of probability and statistics.
  • Familiarity with the application of calculus to problems in classical physics.
  • Mastery of basic principles of equilibrium thermodynamics and chemical kinetics.
  • Ability to read and analyze primary research literature.

Goals of preparation in biochemistry
Upon graduation, biochemistry majors will be well-placed for:

  • Graduate and postdoctoral study in preparation for careers in biomedical research.
  • Employment in pharmaceutical and biotech companies.
  • Careers in other biologically related areas, such as patent law, public health policy, etc.

Goals for non-majors
The Biochemistry curriculum also serves many students with majors in other departments, particularly Biology, Neuroscience, and Chemistry. Our goals for these students are aimed less at the quantitative mastery of the subjects listed above for majors, and more towards attaining a basic literacy regarding behavior of proteins and nucleic acids in cellular function.

Requirements for the Major

Degree of Bachelor of Science
One year of general chemistry with laboratory; one year of organic chemistry with laboratory; one year of physics taught using calculus (PHYS 11a,b or PHYS 15a,b) with laboratory (PHYS 19a,b); BIOL 14a or 22a with laboratory (Genetics and Genomics); BIOL 15b or 22b with laboratory (Cells and Organisms)--the above courses must be taken prior to the senior year; BCHM 100a (Advanced Introductory Biochemistry), BCHM 101a (Advanced Biochemistry: Enzyme Mechanisms), BCHM 103b (Advanced Biochemistry: Cellular Information Transfer Mechanisms), BCHM 104a (Physical Chemistry of Macromolecules I), BCHM 104b (Physical Chemistry of Macromolecules); and one elective consisting of a biochemistry-related 100-level course (excluding research courses) from any department in the Division of Science. The course used to fulfill the elective requirement must be approved in advance by the Undergraduate Advising Head. In some cases, courses below 100-level in mathematics or statistics can be used to fulfill the elective requirement if approved by the Undergraduate Advising Head. CHEM 141a (Classical and Statistical Thermodynamics) may be substituted for BCHM 104a with approval of the Undergraduate Advising Head.

No course used to fulfill major requirements may be taken pass/fail. Grades below C- cannot be used to fulfill the requirements for the major. The advanced courses required for the Biochemistry major are demanding and require a strong background in Chemistry, Physics, and Mathematics. Biochemistry majors are typically students with excellent performance in the introductory courses in these subjects.

Senior Honors Program
In addition to the degree requirements listed previously, departmental honors require completion of eight credits of BCHM 99 (Research for Undergraduates), submission of an acceptable research thesis, and a final GPA 3.00 or better in the sciences and mathematics. Honors candidates are also expected to give a short oral presentation of their thesis research to members of the department at the end of their senior year. BCHM 99 may not exceed 12 credits. Petition to the department for participation in the honors program is made at or before the beginning of the senior year.

Combined BS/MS Program

In addition to all courses required for the BS degree, the BS/MS degree requires completion of BCHM 102a (Quantitative Approaches to Biochemical Systems) one additional 100-level elective (excluding research courses) approved in advance by the Undergraduate Advising Head, four semesters of research courses (consisting of one or two semesters of BCHM 99 plus two or three semesters of BCHM 150), a full-time (i.e., no concurrent course work) summer research residency lasting at least ten weeks, submission of an acceptable thesis, a GPA of 3.00 or better in the sciences and mathematics, and grades of B- or better in all courses used for the major.

The BS/MS program requires completion of thirty-eight courses and the total credits required for the BS/MS degree is 152; no more than 24 credits of research (BCHM 99 or BCHM 150) can count toward this total. In addition, students must complete at least four graduate-level courses beyond the courses used by that student to fulfill the requirements for any undergraduate major (including the Biochemistry BS). BCHM 102a and BCHM 150 courses can be used to fulfill this four-course requirement. Application to the BS/MS program is made to the department no later than the last day of classes in the first semester of the junior year, and all work, including the thesis, must be completed by the time the BS is awarded.

To qualify for the BS/MS degree, the thesis must constitute a significant research contribution; if a thesis is found to be unacceptable under the BS/MS program, it will automatically be considered under the honors program. The BS/MS thesis must be deposited electronically to the Robert D. Farber University Archives at Brandeis.

In order to complete the honors program or the combined BS/MS program, it is advisable to gain exemption where possible from introductory courses in science and mathematics. This is especially important for the premedical students who must also fulfill the requirements imposed by medical schools.
