Minor in Biology

Coursework for the minor in Biology consists of two foundational courses in introductory biology followed by a highly flexible range of options in one or more specific fields, such as cell and molecular biology, neurobiology and behavior, or ecology and evolution. Students may choose to obtain greater breadth of understanding in biology, or focus on one area of particular interest. The minor serves as an excellent complement to related sciences, such as chemistry, earth & environment, physics, psychological & brain sciences, and human physiology, providing a different perspective that enhances a student’s appreciation and understanding of the material encountered in their chosen major.

The minor in Biology is an excellent stepping-stone to further education in the life sciences, which in turn may lay the groundwork for future participation in various health-related professions and other pursuits.


A minor in Biology consists of five courses. At least three of these courses must be taken in the BU Biology Department (or be cross-listed with BI courses in CAS or MET).

Students must receive a grade of C or higher in all five courses taken toward the minor.

Required Courses

  • CAS BI 107 (or CGS NS 201)
  • CAS BI 108 (or BI 116)
  • Three Biology electives*

* These electives can be any 4-credit courses offered by the Biology Department, including CAS BB 522 and/or eligible courses under the Optional Programs section of the Biology Bulletin page. Please note the following exceptions (which cannot be used toward the minor):

  • CAS/MET BI 105
  • CAS/MET BI 106
  • CAS BI 114
  • CAS BI 119
  • CAS BI 194
  • CAS BI 196
  • CAS/MET BI 210
  • CAS/MET BI 211


Students may use advanced credit (e.g., AP credit) to satisfy the BI 107 and/or BI 108 requirement.

Up to two of the three electives for the minor may be Non-Departmental Courses outside the Biology Department.

Up to one 4-credit Undergraduate Research in Biology semester may be used as an elective for the minor.
