Molecular biology emphasizes the study of molecules that make up an organism, how they interact, and how they are controlled. With the development of the field of genomics, biologists also study organisms at the whole genome level. Molecular biology and genomics are applied within all biological disciplines, including biochemistry, cell biology, and developmental biology. Positions for molecular biologists are available in the biotechnology industries as well as in universities, medical schools, hospitals, government laboratories, research institutes, and public health institutions.

The Molecular Biology undergraduate major also incorporates the requirements expected for admission to medical, dental, and other health professional schools and to graduate schools in cell and molecular biology, biochemistry, and related disciplines. A graduate program in Molecular, Cellular & Developmental Biology (MCDB) is also offered.
