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 4-credit courses. At least three of these courses must be taken in the Department of Biology at Boston University.

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

Required Courses

  • CAS BI 107
  • CAS BI 108
  • Three additional biology (BI) or BI cross-listed courses. (Two of these courses may be “Optional Related Courses” outside the department if three of the five minor courses are taken in the Biology Department at BU.)

Students may use AP credits to satisfy the BI 107 and/or BI 108 requirement.

Note: Only courses that are approved for the BA in Biology may count toward a Biology minor. The following biology courses do not count toward the minor in Biology:

  • CAS BI 105
  • CAS BI 106
  • CAS BI 111
  • CAS BI 114
  • CAS BI 119
  • CAS BI 211
