Molecular and Cellular Biology Major Requirements (B.S.)

(Also see Requirements for a Bachelor's Degree.)

The Biology Department offers a B.S. degree in molecular and cellular biology. The B.S. program is designed to provide a rigorous preparation for advanced study in the biomedical sciences. The program is tailored not only to students planning to enter Ph.D. programs or obtain employment in the biotechnology industry but also for premedical students.

All courses required for the molecular and cellular biology major must be taken for a letter grade (not S/U) and be passed with a grade of C- or better with one exception. The department will accept one passing grade below C- in senior year provided that the average for all formal lecture and laboratory courses is at least 2.0.

Honors in Molecular and Cellular Biology

Students completing the B.S. in molecular and cellular biology major are eligible to receive their degree with honors.

The B.S. in molecular and cellular biology with honors requires, in addition to the regular requirements for the major, a 3.5 GPA for natural sciences and quantitative studies courses, a presentation of a poster describing the independent research, and a recommendation from the research sponsor.

The research requirement must be completed under the direction of a faculty member in a department associated with the Johns Hopkins University or the Johns Hopkins Medical Institutions. If the student’s research director for independent research is not a member of the Department of Biology, a Biology faculty member must serve as a sponsor and approve the recommendation from the research director.
