BA in Biochemistry & Molecular Biology

The Biochemistry & Molecular Biology (BMB) major provides students with a strong foundation in biology and chemistry followed by the opportunity to focus on particular aspects of these disciplines through electives and undergraduate research. Laboratory work is stressed throughout, since biochemistry and molecular biology are experimental sciences that require a broad range of practical skills. Upper-level courses emphasize state-of-the-art research and experimental techniques used to probe the structures and functions of biologically important molecules from the intracellular to systems levels. The BMB curriculum provides exceptional preparation for pursuing advanced degrees in the biomedical sciences as well as entering the biotechnology workforce.


All students entering as freshmen in Fall 2018 and after will pursue coursework in the BU Hub, a general education program that is integrated into the entire undergraduate experience. BU Hub requirements are flexible and can be satisfied in many different ways, through coursework in and beyond the major and, in some cases, through co-curricular activities. Students majoring in Biochemistry & Molecular Biology (BMB) will ordinarily, through coursework in the major, satisfy BU Hub requirements in Scientific Inquiry and Quantitative Reasoning, as well as some of the requirements in the Intellectual Toolkit. Remaining BU Hub requirements will be satisfied by selecting from a wide range of available courses outside the major or, in some cases, co-curricular experiences.

The BMB major requires a minimum of 14 biology and chemistry courses. Students must also complete a total of four related courses in math and physics.

A grade of C or higher is required in all courses taken for credit in the major.

Course titles and full descriptions are located in the Courses portion of this Bulletin. Unless otherwise noted, all required courses are 4 credit hours.

Sophomore BB 291/292 2 credits
Junior BB 391/392 2 or 4 credits
Senior BB 491/492 4 credits


  • Students must have a 3.0 GPA in BMB major courses to participate in Undergraduate Research in BMB
  • Senior-level research (including Honors) can be used to satisfy the advanced lab elective if both semesters of research are taken.
  • Students can use one semester of 4-credit research to fulfill a BMB elective if not using research courses to complete the advanced lab elective.
  • Seniors may pursue Honors Research in BMB; see Honors section below.

Please visit the BMB website for additional information on undergraduate research.
