 BS in Biology Major and Minor Requirements

Biology Major Requirements

34 credit hours of biology, including at least one 400-level course (excluding BL 478). Courses are to be chosen with advisory approval and always include applicable laboratory corequisites. CH 431 will be accepted toward the 34 credit-hour requirement.

Introductory Sequence

Must complete BL 155, 156, 157, 158, 159, and 160

Molecule to Cell

At least one chosen from BL 213, 301, 310, 465, 470

Cell to Organism

At least one chosen from BL 230 and 231, 250, 254, 308, 360, 410, 420, 450, 459, 471, 475.

Organism to Biosphere

At least one chosen from BL 206, 222, 370, 424, 425, 435, 440, 442, 444, 445, 447.

Required Support Courses CH 141-144 (or 151H, 153); CH 221-224; MT 135, and MT 228.

Strongly Recommended

CH 141-144, 221-224, which can be prerequisites for advanced biology courses.

BL 155-160 is the normal first-and-second-year sequence for biology majors.  If, for some reason acceptable to the department, BL 157, 158, and 160 are taken separately from BL 155, 156, 159, the student is expected to take BL 155, 156, and 159 or their equivalents before taking the laboratory courses.

Biology Minor Requirements
