Undergraduate Program


The undergraduate major in Molecular and Cell Biology (MCB) focuses on the study of molecular structures and processes of cellular life and their roles in the function, reproduction, and development of living organisms. This covers a broad range of specialized disciplines, such as biochemistry, microbiology, biophysics, molecular biology, genetics, cell physiology, cell anatomy, immunology, and neurobiology. The types of living organisms from which the departmental faculty draws its working materials are as diverse as its disciplinary specializations, ranging from viruses and microbes through plants, roundworms, annelids, arthropods, and mollusks, to fish, amphibia, and mammals. 

There are five emphases to choose from Biochemistry & Molecular Biology, Cell & Developmental Biology, Genetics, Genomics & Development, Immunology & Pathogenesis, and Neurobiology. Information about the emphases, including the lower-division and upper division requirements, can be found on the Major-At-Glance webpage
Career Paths
Students majoring in any of these emphases have been highly successful in entering graduate or medical school and in other science- and health-related careers.  For more information about what our students do with an MCB major, check out our Career webpage.
