Two courses required for the Biomedical Sciences track are not offered in a fully-online format: CHEM 243A Organic Chemistry Lab I (1-unit) and CHEM 243B Organic Chemistry Lab II (1-unit). Students on this track will need to take both courses at UArizona during the summer intensive in presession (available starting Summer 2022) or an alternative institution for equivalent transfer credit. Note: We recommend the Biomedical Sciences track for students who intend to apply to professional health programs post-graduation.

About the Program
The Bachelor of Science in Biology is offered by our top-ranked program renowned for groundbreaking scientific discoveries and a long tradition of involving students in leading-edge research. This degree is for students interested in biodiversity and the natural world who want the flexibility to pursue careers in medicine, health, agriculture and environment. The curriculum provides a broad overview of the structure, function, and evolution of biological systems from component parts—molecules and cells—to organisms, communities and ecosystems. Biology majors choose from two degree emphases: Biomedical Sciences and Organismal Biology.
The online Bachelor’s degree in Biology can be completed fully online. However, some post-graduate professional programs do not accept prerequisite courses taken online. Be sure to check the policies for post-graduate programs you may want to attend.
Biomedical Sciences
The Biomedical Sciences emphasis is for students who plan to pursue careers in biomedical research, pre-med students interested in medicine and other health professions. The program of study provides training in systems biology with a focus on anatomy, physiology and biochemistry, and includes all of the coursework covered on the MCAT and required for admission to medical school.
