BIOCHEMISTRY AND MOLECULAR BIOLOGY PROGRAM
Program Director: Dr. Joseph Wu (M.S. students) and Dr. Yuk-Ching
Tse-Dinh (Ph.D. students)
The Department of Biochemistry and Molecular Biology offers programs leading
to the Master of Science and Doctor of Philosophy degrees. The objective of
these programs is to provide students with a thorough background in modern
biochemistry and molecular biology. This theoretical background provides the
fundamental knowledge necessary for an understanding of the life sciences at the
molecular level.
The doctoral program prepares students for a career in independent research
or teaching in academia, government, or industry. Doctoral students are
introduced to laboratory research early in their course of study. Research
opportunities in the department are in the areas of protein structure and
function, enzyme reaction mechanisms, regulation of gene expression, mechanism
of hormone action and cell signaling, enzymology and mechanisms of DNA
replication and repair, cell cycle regulation, control of cell growth, molecular
biology of the cancer process, molecular neurobiology, and the genetics and
biochemistry of bacterial and viral pathogens. A common theme of the research
programs is the application of modern recombinant DNA technology to the study of
gene regulation and protein structure-function relationships. Specific admission
requirements for the Ph.D. include: one year each of inorganic chemistry,
organic chemistry, physics, biology and mathematics at the undergraduate levels.
A year of physical chemistry is also recommended.
The Master’s program provides advanced training in the principles of
biochemistry and molecular biology. Research opportunities are available (Plan
B). Recent graduates from the Master’s program have found technical positions in
academic and pharmaceutical company labs, pursued careers in teaching, science
writing and editing, and as scientific consultants in business settings, or have
gone on to advanced studies for the Ph.D. or M.D. degrees.

During the first year, the student takes General Biochemistry I (BIOC 1010)
and Biochemistry of Gene Expression (BIOC 1250) in the Fall term and General
Biochemistry II (BIOC 1020) and Protein Structure and Function (BIOC 2690) in
the Spring term. Departmental Seminar and Journal Club (BIOC 8020) is required
during each year of enrollment in the Ph.D. program but only four credits of
this course may be applied towards the program’s minimum credit requirements.
All Ph.D. students are required and expected to attend departmental seminars.
These seminars include those presented by students and invited speakers. In
addition, Ph.D. students will carry out three laboratory rotations of
approximately three months each during the first year (BIOC 9110). Since the
academic load in the Spring term is fairly heavy and Part I of the Qualifying
Examination (the Preliminary Examination) is taken in June of the first year,
the third rotation may be extended into the summer.
M.D./Ph.D. Candidates
Course requirements for M.D./Ph.D. candidates seeking their Ph.D. in
Biochemistry and Molecular Biology are Cell Biology (BIOC 1360), Biochemistry of
Gene Expression (BIOC 1250), and Protein Structure and Function (BIOC 2690).
Departmental Seminar and Journal Club (BIOC 8020) is required during each year
of enrollment in the Ph.D. program. Students may elect to take additional
courses offered in other departments. M.D./Ph.D. students must also pass the
written and oral examination(s), prepare a thesis proposal, and defend a
doctoral dissertation like all Ph.D. candidates.
Qualifying Examination
Part I of the Qualifying Examination (the Preliminary Exam) is administered
at the end of the first year (usually in June). This written examination tests
the student's mastery of material covered in the first-year curriculum and other
selected topics. All first year students must take the examination at this time.
Under certain circumstances, if performance on the examination is
unsatisfactory, a student may be given the opportunity to re-take the
examination within one year. No more than two opportunities to pass the
examination will be provided.
Part II (Qualifying Exam): Within one year of completing Part I of the
examination, the student must submit a short written proposal describing the
design of a research project on a topic not directly related to the student's
dissertation research. An examining committee will be established consisting of
at least three faculty from the program and one faculty member from another
doctoral program within the College. This committee will review and approve the
student’s topic. The proposal will then be presented and defended orally in
front of the examining committee and the department, at which time the student
will be examined on various aspects of the proposal.
Candidacy
The student is considered a doctoral candidate when he or she has passed both
parts of the Qualifying Examination, has earned at least 30 didactic
(letter-graded) credits including all the required courses, and has been
recommended for candidacy by the program faculty. M.D./Ph.D. students are
eligible for candidacy under the same conditions except that the credit
requirement consists only of the required graduate courses.
Dissertation Committee
Students must choose a thesis advisor after successful completion of Part I
(Preliminary Exam) of the Qualifying Examination (i.e., at the end of the first
year). Before the end of the second year, a dissertation committee should be
formed. This committee must have at least five members, including at least three
graduate faculty from the Biochemistry and Molecular Biology program and one
graduate faculty member from another doctoral program. One member of the
committee may be a scientist with appropriate expertise from outside the
College. The thesis advisor chairs the committee. Within a year of beginning the
thesis research, the student should present a dissertation research proposal to
this committee. A written progress report should be presented to the committee
at least once each year. Upon approval of the committee, the student may write
the dissertation and defend it before the committee and the department

| This course is designed to present a thorough background of
structural biochemistry, molecular biology and metabolism. The first
semester provides the underpinning of quantitative biochemistry, i.e.,
stoichiometry, acids, bases, thermodynamics and kinetics. This is followed
by a consideration of the structure and properties of amino acids and
proteins. Fundamentals of catalysis and enzyme properties and mechanisms
follow the development of protein structure. Molecular biology is
developed via consideration of the structure, function and synthesis of DNA,
RNA and proteins. Aspects of information transfer and its control are
discussed in addition to the topics of regulation of gene expression and
biotechnology. Finally, the structure and properties of carbohydrates and
lipids, including glycoproteins, glycolipids and glycosaminoglycans are
presented.
The second semester focuses largely on metabolism. The subject is
introduced by a discussion of the principles governing metabolism including
bioenergetics, compartmentalization, and the operation and control of
pathways. Major metabolic pathways of carbohydrate metabolism are discussed.
This is followed by a consideration of oxidative metabolism and lipid
metabolism (i.e., triglycerides, phospholipids and sterols). This is
followed by signal transduction, membrane biochemistry and biochemistry of
hormones. Then, the metabolism of amino acids, porphyrins and nucleotides
are developed with considerable discussion of inborn errors of metabolism.
The course concludes with a discussion of nutritional biochemistry and
integration of pathways.
Normally, Part I is a prerequisite for Part II. The order of a student’s
enrollment may be reversed with the approval of the instructor if the
student has received adequate training in physical chemistry and molecular
biology. Lectures and conferences: 4 hrs/wk. Letter-graded.
